141-517: The history of multiplayer video games extends over several decades, tracing back to the emergence of electronic gaming in the mid-20th century. One of the earliest instances of multiplayer interaction was witnessed with the development of Spacewar! in 1962 for the DEC PDP-1 computer by Steve Russell and colleagues at the MIT . During the late 1970s and early 1980s, multiplayer gaming gained momentum within

282-1037: A Local Area Network (LAN) version, 1991's Spectre for the Apple Macintosh, featured AppleTalk support for up to eight players. Spectre's popularity was partially attributed to the display of a player's name above their cybertank. There followed 1993's Doom , whose first network version allowed four simultaneous players. Play-by-email multiplayer games use email to communicate between computers. Other turn-based variations not requiring players to be online simultaneously are Play-by-post gaming and Play-by-Internet . Some online games are " massively multiplayer ", with many players participating simultaneously. Two massively multiplayer genres are MMORPG (such as World of Warcraft or EverQuest ) and MMORTS . First-person shooters have become popular multiplayer games; Battlefield 1942 and Counter-Strike have little (or no) single-player gameplay. Developer and gaming site OMGPOP 's library included multiplayer Flash games for

423-401: A dogfight while maneuvering in the gravity well of a star. Both ships are controlled by human players. Each ship has limited weaponry and fuel for maneuvering, and the ships remain in motion even when the player is not accelerating. Flying near the star to provide a gravity assist was a common tactic. Ships are destroyed when they collide with a torpedo, the star, or each other. At any time,

564-455: A first-person perspective version played on two screens that simulates each pilot's view out of the cockpit. Some of these Spacewar! installations also replicated Saunders' gamepad. DEC learned about the game soon after its creation, and gave demonstrations of it running on their PDP-1, as well as publishing a brochure about the game and the computer in 1963. According to a second-hand account heard by Russell while working at DEC, Spacewar!

705-519: A sigil , and values are often identified as strings by being delimited by "double quotation marks". Arrays in BASIC could contain integers, floating point or string variables. Some dialects of BASIC supported matrices and matrix operations , which can be used to solve sets of simultaneous linear algebraic equations. These dialects would directly support matrix operations such as assignment, addition, multiplication (of compatible matrix types), and evaluation of

846-519: A visual forms builder . This reignited use of the language and "VB" remains a major programming language in the form of VB.NET , while a hobbyist scene for BASIC more broadly continues to exist. John G. Kemeny was the chairman of the Dartmouth College Mathematics Department. Based largely on his reputation as an innovator in math teaching, in 1959 the college won an Alfred P. Sloan Foundation award for $ 500,000 to build

987-461: A wide area network (a common example being the Internet). Unlike local multiplayer, players playing online multiplayer are not restricted to the same local network. This allows players to interact with others from a much greater distance. Playing multiplayer online offers the benefits of distance, but it also comes with its own unique challenges. Gamers refer to latency using the term " ping ", after

1128-742: A $ 300,000 grant from the National Science Foundation , which was used to purchase a GE-225 computer for processing, and a Datanet-30 realtime processor to handle the Teletype Model 33 teleprinters used for input and output. A team of a dozen undergraduates worked on the project for about a year, writing both the DTSS system and the BASIC compiler. The first version BASIC language was released on 1 May 1964. Initially, BASIC concentrated on supporting straightforward mathematical work, with matrix arithmetic support from its initial implementation as

1269-669: A BASIC for the PDP-8 , which was a major success in the education market. By the early 1970s, FOCAL and JOSS had been forgotten and BASIC had become almost universal in the minicomputer market. DEC would go on to introduce their updated version, BASIC-PLUS , for use on the RSTS/E time-sharing operating system. During this period a number of simple text-based games were written in BASIC, most notably Mike Mayfield's Star Trek . David Ahl collected these, some ported from FOCAL, and published them in an educational newsletter he compiled. He later collected

1410-477: A LAN. This involves multiple devices using one local network to play together. Networked multiplayer games on LAN eliminate common problems faced when playing online such as lag and anonymity. Games played on a LAN network are the focus of LAN parties . While local co-op and LAN parties still take place, there has been a decrease in both due to an increasing number of players and games utilizing online multiplayer gaming. Online multiplayer games connect players over

1551-472: A batch language, and character string functionality being added by 1965. Usage in the university rapidly expanded, requiring the main CPU to be replaced by a GE-235, and still later by a GE-635. By the early 1970s there were hundreds of terminals connected to the machines at Dartmouth, some of them remotely. Wanting use of the language to become widespread, its designers made the compiler available free of charge. In

1692-671: A cable. Their article includes a type-in , two-player Hangman , and describes the authors' more-sophisticated Flash Attack . SuperSet Software 's Snipes (1981) uses networking technology that would become Novell NetWare . Digital Equipment Corporation distributed another multi-user version of Star Trek , Decwar , without real-time screen updating; it was widely distributed to universities with DECsystem-10s. In 1981 Cliff Zimmerman wrote an homage to Star Trek in MACRO-10 for DECsystem-10s and -20s using VT100-series graphics. "VTtrek" pitted four Federation players against four Klingons in

1833-415: A collaborative environment without concern for ownership or copyright, which led to a group effort to elaborate on Russell's initial Spacewar! game. Consequently, since the inaccuracy and lack of realism in the starfield annoyed TMRC member Peter Samson, he wrote a program based on real star charts that scrolled slowly through the night sky, including every star in a band between 22.5° N and 22.5° S down to

1974-466: A determinant. Many microcomputer BASICs did not support this data type; matrix operations were still possible, but had to be programmed explicitly on array elements. New BASIC programmers on a home computer might start with a simple program, perhaps using the language's PRINT statement to display a message on the screen; a well-known and often-replicated example is Kernighan and Ritchie 's "Hello, World!" program : An infinite loop could be used to fill

2115-449: A drastically different way, with different mechanics, a different type of objective, or both. Examples of games with strong asymmetry include Dead by Daylight , Evolve , and Left 4 Dead . Asynchronous multiplayer is a form of multiplayer gameplay where players do not have to be playing at the same time. This form of multiplayer game has its origins in play-by-mail games , where players would send their moves through postal mail to

2256-474: A game master, who then would compile and send out results for the next turn. Play-by-mail games transitioned to electronic form as play-by-email games. Similar games were developed for bulletin board systems , such as Trade Wars , where the turn structure may not be as rigorous and allow players to take actions at any time in a persistence space alongside all other players, a concept known as sporadic play. These types of asynchronous multiplayer games waned with

2397-410: A loop: DO 100 , I = 1 , 10 , 2 . Is it '1, 10, 2' or '1, 2, 10', and is the comma after the line number required or not?" Moreover, the lack of any sort of immediate feedback was a key problem; the machines of the era used batch processing and took a long time to complete a run of a program. While Kurtz was visiting MIT , John McCarthy suggested that time-sharing offered a solution;

2538-455: A machine capable of running between 16 and 32 users at the same time. The system, bundled as the HP 2000, was the first mini platform to offer time-sharing and was an immediate runaway success, catapulting HP to become the third-largest vendor in the minicomputer space, behind DEC and Data General (DG). DEC, the leader in the minicomputer space since the mid-1960s, had initially ignored BASIC. This

2679-493: A monitor and many of the remainder to secure military locations or research labs with no free computer time, which prevented the original Spacewar! from reaching beyond a narrow, academic audience. Though some later DEC models, such as the PDP-6 , came with Spacewar! pre-loaded , the audience for the game remained very limited; the PDP-6, for example, sold only 23 units. Spacewar!

2820-415: A multiple-system, multiplayer mode. Turn-based games such as chess also lend themselves to single system single screen and even to a single controller. Multiple types of games allow players to use local multiplayer. The term "local co-op" or "couch co-op" refers to local multiplayer games played in a cooperative manner on the same system; these may use split-screen or some other display method. Another option

2961-417: A new department building. Thomas E. Kurtz had joined the department in 1956, and from the 1960s Kemeny and Kurtz agreed on the need for programming literacy among students outside the traditional STEM fields. Kemeny later noted that "Our vision was that every student on campus should have access to a computer , and any faculty member should be able to use a computer in the classroom whenever appropriate. It

3102-403: A number of console , and personal computer games too. Local multiplayer games played on a singular system sometimes use split screen , so each player has an individual view of the action (important in first-person shooters and in racing video games ) Nearly all multiplayer modes on beat 'em up games have a single-system option, but racing games have started to abandon split-screen in favor of

3243-433: A number of these into book form, 101 BASIC Computer Games , published in 1973. During the same period, Ahl was involved in the creation of a small computer for education use, an early personal computer . When management refused to support the concept, Ahl left DEC in 1974 to found the seminal computer magazine, Creative Computing . The book remained popular, and was re-published on several occasions. The introduction of

3384-401: A prior exposure to BASIC: as potential programmers they are mentally mutilated beyond hope of regeneration", BASIC was one of the few languages that was both high-level enough to be usable by those without training and small enough to fit into the microcomputers of the day, making it the de facto standard programming language on early microcomputers. The first microcomputer version of BASIC

3525-547: A program running on each terminal (for each player), sharing a segment of shared memory (known as the "high segment" in the OS TOPS-10). The games became popular, and the university often banned them because of their RAM use . STAR was based on 1974's single-user, turn-oriented BASIC program STAR, written by Michael O'Shaughnessy at UNH. Wasserman and Stryker in 1980 described in BYTE how to network two Commodore PET computers with

3666-445: A program that functioned equally well as an entertainment experience for the players and as a demonstration for spectators: to use as much of the computer's resources as possible, to be consistently interesting and therefore have every run be different, and to be entertaining and therefore a game. It took Russell, with assistance from the other programmers—including Bob Saunders and Steve Piner (but not Wiitanen, who had been called up by

3807-430: A prototype coin-operated computer game, Galaxy Game , with a US$ 20,000 (equivalent to about $ 150,000 in 2023) PDP-11 , though they never produced more than two prototypes exhibited at Stanford. Around the same time, a second prototype coin-operated game based on Spacewar! , Computer Space , was developed by Nolan Bushnell and Ted Dabney , which would become the first commercially sold arcade video game and

3948-421: A ship moves past one edge of the screen, it reappears on the other side in a wraparound effect. A hyperspace feature, or "panic button", can be used as a last-ditch means to evade enemy torpedoes by moving the player's ship to another location on the screen after it disappears for a few seconds, but the reentry from hyperspace occurs at a random location, and in some versions there is an increasing probability of

4089-426: A significantly different experience of the game. In games with light asymmetry, the players share some of the same basic mechanics (such as movement and death), yet have different roles in the game; this is a common feature of the multiplayer online battle arena (MOBA) genre such as League of Legends and Dota 2 , and in hero shooters such as Overwatch and Apex Legends . A first-person shooter that adopts

4230-608: A single computer were STAR (based on Star Trek ), OCEAN (a battle using ships, submarines and helicopters, with players divided between two combating cities) and 1975's CAVE (based on Dungeons & Dragons ), created by Christopher Caldwell (with artwork and suggestions by Roger Long and assembly coding by Robert Kenney) on the University of New Hampshire 's DECsystem-10 90. The university's computer system had hundreds of terminals, connected (via serial lines) through cluster PDP-11s for student, teacher, and staff access. The games had

4371-463: A single machine could divide up its processing time among many users, giving them the illusion of having a (slow) computer to themselves. Small programs would return results in a few seconds. This led to increasing interest in a system using time-sharing and a new language specifically for use by non-STEM students. Kemeny wrote the first version of BASIC. The acronym BASIC comes from the name of an unpublished paper by Thomas Kurtz. The new language

4512-406: A smaller introductory version with the initial releases of the machines and a Microsoft-based version introduced as interest in the platforms increased. As new companies entered the field, additional versions were added that subtly changed the BASIC family. The Atari 8-bit computers use the 8 KB Atari BASIC which is not derived from Microsoft BASIC. Sinclair BASIC was introduced in 1980 with

4653-491: A tape containing the code, slammed it down in front of Russell, and asked what other excuses he had. Russell, later explaining that "I looked around and I didn't find an excuse, so I had to settle down and do some figuring", started writing the code around the time that the PDP-1's display was installed at the end of December 1961. The game was developed to meet three precepts Russell, Graetz, and Wiitanen had developed for creating

4794-604: A tenement building on Hingham Street in Cambridge, Massachusetts . "We had this brand new PDP-1", Russell told Rolling Stone in a 1972 interview. "Somebody [ Marvin Minsky ] had built some little pattern-generating programs which made interesting patterns like a kaleidoscope . Not a very good demonstration. Here was this display that could do all sorts of good things! So we started talking about it, figuring what would be interesting displays. We decided that probably you could make

4935-503: A three-dimensional universe. Flight Simulator II , released in 1986 for the Atari ST and Commodore Amiga, allowed two players to connect via modem or serial cable and fly together in a shared environment. MIDI Maze , an early first-person shooter released in 1987 for the Atari ST , featured network multiplay through a MIDI interface before Ethernet and Internet play became common. It

5076-610: A time limit, the hyperspace function, and a larger, second screen for viewers at the demonstration, and in May Graetz presented a paper about the game, "SPACEWAR! Real-Time Capability of the PDP-1", at the first meeting of the Digital Equipment Computer Users' Society . The demonstration was a success, and the game proved very popular at MIT; the laboratory that hosted the PDP-1 soon banned play except during lunch and after working hours. Visitors such as Frederik Pohl ,

5217-460: A torpedo launch button. The button was silent so that the opposing player would not have a warning that the player was attempting to fire a torpedo during a cooldown period. Russell, Graetz and Wiitanen developed the basic Spacewar! concept in the summer of 1961, in anticipation of the PDP-1 being installed. Russell had recently finished reading the Lensman series by E. E. "Doc" Smith and thought

5358-452: A two-dimensional maneuvering sort of thing, and decided that naturally the obvious thing to do was spaceships." The gameplay of Spacewar! involves two monochrome spaceships called "the needle" and "the wedge", each controlled by a player, attempting to shoot one another while maneuvering on a two-dimensional plane in the gravity well of a star, set against the backdrop of a starfield. The ships fire torpedoes, which are not affected by

5499-400: A utility which measures round-trip network communication delays (by the use of ICMP packets). A player on a DSL connection with a 50- ms ping can react faster than a modem user with a 350-ms average latency. Other problems include packet loss and choke, which can prevent a player from "registering" their actions with a server. In first-person shooters, this problem appears when bullets hit

5640-556: A version of the MS code, or quickly introduced new models with it. Ohio Scientific's personal computers also joined this trend at that time. By 1978, MS BASIC was a de facto standard and practically every home computer of the 1980s included it in ROM . Upon boot, a BASIC interpreter in direct mode was presented. Commodore Business Machines includes Commodore BASIC , based on Microsoft BASIC. The Apple II and TRS-80 each have two versions of BASIC:

5781-554: A wide variety of Tiny BASICs with added features or other improvements, with versions from Tom Pittman and Li-Chen Wang becoming particularly well known. Micro-Soft, by this time Microsoft , ported their interpreter for the MOS 6502 , which quickly become one of the most popular microprocessors of the 8-bit era. When new microcomputers began to appear, notably the "1977 trinity" of the TRS-80 , Commodore PET and Apple II , they either included

Players rotate using the input device to perform their turn such that each is taking a turn on the "hot-seat". Not all local multiplayer games are played on the same console or personal computer. Some local multiplayer games are played over

At the time, nearly all computers required writing custom software, which only scientists and mathematicians tended to learn. In addition to

There followed ports to a number of platforms (including Game Boy and Super NES ) in 1991 under the title Faceball 2000 , making it one of the first handheld, multi-platform first-person shooters and an early console example of the genre. Networked multiplayer gaming modes are known as "netplay". The first popular video-game title with

This category of games requires multiple machines to connect via the Internet; before the Internet became popular, MUDs were played on time-sharing computer systems and games like Doom were played on a LAN. Beginning with the Sega NetLink in 1996, Game.com in 1997 and Dreamcast in 2000, game consoles support network gaming over LANs and

7473-477: The HP2000 series in the late 1960s and continuing sales into the 1980s. Many early video games trace their history to one of these versions of BASIC. The emergence of microcomputers in the mid-1970s led to the development of multiple BASIC dialects, including Microsoft BASIC in 1975. Due to the tiny main memory available on these machines, often 4 KB, a variety of Tiny BASIC dialects were also created. BASIC

7614-523: The Nintendo 3DS and Nintendo DSi called Petit Computer allows for programming in a slightly modified version of BASIC with DS button support. A version has also been released for Nintendo Switch , which has also been supplied a version of the Fuze Code System, a BASIC variant first implemented as a custom Raspberry Pi machine. Previously BASIC was made available on consoles as Family BASIC (for

7755-522: The Nintendo Famicom ) and PSX Chipmunk Basic (for the original PlayStation ), while yabasic was ported to the PlayStation 2 and FreeBASIC to the original Xbox . Variants of BASIC are available on graphing and otherwise programmable calculators made by Texas Instruments ( TI-BASIC ), HP ( HP BASIC ), Casio ( Casio BASIC ), and others.

That early version also contained a randomly generated background star field, initially added by Russell because a blank background made it difficult to tell the relative motion of the two spaceships at slow speeds. The programming community in the area, including the Hingham Institute and the TMRC, had developed what was later termed the " hacker ethic ", whereby all programs were freely shared and modified by other programmers in

8037-943: The QB64 and FreeBASIC implementations. In 2013 a game written in QBasic and compiled with QB64 for modern computers entitled Black Annex was released on Steam . Blitz Basic , Dark Basic , SdlBasic , Super Game System Basic , PlayBASIC , CoolBasic , AllegroBASIC , ethosBASIC , GLBasic and Basic4GL further filled this demand, right up to the modern RCBasic , NaaLaa , AppGameKit , Monkey 2 and Cerberus-X . In 1991, Microsoft introduced Visual Basic , an evolutionary development of QuickBASIC . It included constructs from that language such as block-structured control statements, parameterized subroutines and optional static typing as well as object-oriented constructs from other languages such as "With" and "For Each". The language retained some compatibility with its predecessors, such as

Minimal versions of BASIC had only integer variables and one- or two-letter variable names, which minimized requirements of limited and expensive memory (RAM). More powerful versions had floating-point arithmetic, and variables could be labelled with names six or more characters long. There were some problems and restrictions in early implementations; for example, Applesoft BASIC allowed variable names to be several characters long, but only

Likewise, the cryptic IF statement of Fortran, whose syntax matched a particular instruction of the machine on which it was originally written, became the simpler IF I = 5 THEN GOTO 100 . These changes made the language much less idiosyncratic while still having an overall structure and feel similar to the original FORTRAN. The project received

9306-487: The History of Electronic Games . During the 1950s, various computer games were created in the context of academic computer and programming research and for demonstrations of computing power, especially after the introduction later in the decade of smaller and faster computers on which programs could be created and run in real time as opposed to being executed on a schedule . A few programs, however, were intended both to showcase

9447-467: The Internet. Over time the number of people playing video games has increased. In 2020, the majority of households in the United States have an occupant that plays video games, and 65% of gamers play multiplayer games with others either online or in person. For some games, "multiplayer" implies that players are playing on the same gaming system or network. This applies to all arcade games , but also to

9588-495: The Internet. Many mobile phones and handheld consoles also offer wireless gaming with Bluetooth (or similar) technology. By the early 2010s online gaming had become a mainstay of console platforms such as Xbox and PlayStation . During the 2010s, as the number of Internet users increased, two new video game genres rapidly gained worldwide popularity – multiplayer online battle arena and battle royale game , both designed exclusively for multiplayer gameplay over

Products as late as the 1990 computer game Star Control drew direct inspiration from Spacewar! . Russell has been quoted as saying that the aspect of the game that he was most pleased with was the number of other programmers it inspired to write their own games without feeling restricted to using Russell's own code or design. On March 12, 2007, The New York Times reported that Spacewar!

10011-620: The arcade scene with classics like Pong and Tank . The transition to home gaming consoles in the 1980s further popularized multiplayer gaming. Titles like Super Mario Bros. for the NES and Golden Axe for the Sega Genesis introduced cooperative and competitive gameplay. Additionally, LAN gaming emerged in the late 1980s, enabling players to connect multiple computers for multiplayer gameplay, popularized by titles like Doom and Warcraft: Orcs & Humans . Players can also play together in

Ken Wasserman and Tim Stryker identified three factors which make networked computer games appealing: John G. Kemeny wrote in 1972 that software running on the Dartmouth Time-Sharing System (DTSS) had recently gained the ability to support multiple simultaneous users, and that games were the first use of the functionality. DTSS's popular American football game, he said, now supported head-to-head play by two humans. The first large-scale serial sessions using

10293-403: The article prompted Microsoft to develop and release Small Basic ; it also inspired similar projects like Basic-256 and the web based Quite Basic. Dartmouth held a 50th anniversary celebration for BASIC on 1 May 2014. The pedagogical use of BASIC has been followed by other languages, such as Pascal , Java and particularly Python . Dartmouth College celebrated the 50th anniversary of

10434-424: The asymmetrical multiplayer system is Tom Clancy's Rainbow Six Siege . Giving players their own special operator changes every player's experience. This puts an emphasis on players improvising their own game plan given the abilities their character has. In games with stronger elements of asymmetry, one player/team may have one gameplay experience (or be in softly asymmetric roles) while the other player or team play in

10575-461: The blink of an eye" even using a "slow" language, as long as large amounts of data were not involved. Many small business owners found they could create their own small, yet useful applications in a few evenings to meet their own specialized needs. Eventually, during the lengthy lifetime of VB3, knowledge of Visual Basic had become a marketable job skill. Microsoft also produced VBScript in 1996 and Visual Basic .NET in 2001. The latter has essentially

10716-505: The business-focused CP/M computers which soon became widespread in small business environments, Microsoft BASIC ( MBASIC ) was one of the leading applications. In 1978, David Lien published the first edition of The BASIC Handbook: An Encyclopedia of the BASIC Computer Language , documenting keywords across over 78 different computers. By 1981, the second edition documented keywords from over 250 different computers, showcasing

10857-404: The casual player until it was shut down in 2013. Some networked multiplayer games, including MUDs and massively multiplayer online games (MMOs) such as RuneScape , omit a single-player mode. The largest MMO in 2008 was World of Warcraft , with over 10 million registered players worldwide. World of Warcraft would hit its peak at 12 million players two years later in 2010, and in 2023 earned

10998-465: The computer's control and power switches. The location of the switches also left one player off to one side of the CRT display due to the limited space in front of the computer, which left them at a disadvantage. To alleviate these problems, Saunders created a detached control device, essentially an early gamepad . The gamepad had a switch for turning left or right, another for forward thrust or hyperspace, and

11139-486: The display with the message: Note that the END statement is optional and has no action in most dialects of BASIC. It was not always included, as is the case in this example. This same program can be modified to print a fixed number of messages using the common FOR...NEXT statement: Most home computers BASIC versions, such as MSX BASIC and GW-BASIC , supported simple data types, loop cycles, and arrays. The following example

11280-456: The drawing functions to free up processing time to calculate the effects of gravity. The initial version of the hyperspace function was limited to three jumps, but carried no risk save possibly re-entering the game in a dangerous position; later versions removed the limit but added the increasing risk of destroying the ship instead of moving it. Additionally, in March 1962, Saunders created gamepads for

11421-453: The early 1970s, Spacewar! migrated from large computer systems to a commercial setting as it formed the basis for the first two coin-operated video games. While playing Spacewar! at Stanford sometime between 1966 and 1969, college student Hugh Tuck remarked that a coin-operated version of the game would be very successful. While the high price of a minicomputer prevented such a game from being feasible then, in 1971 Tuck and Bill Pitts created

11562-496: The editor of Galaxy Science Fiction , enjoyed playing the "lovely game" and wrote that MIT was "borrowing from the science-fiction magazines", with players able to pretend to be Skylark characters. Beginning in mid-1962 and continuing over the next few years, members of the PDP-1 programming community at MIT, including Russell and the other Hingham Institute members, began to spread out to other schools and employers such as Stanford University and DEC, and as they did they spread

11703-449: The emerging field quickly followed suit; Tymshare introduced SUPER BASIC in 1968, CompuServe had a version on the DEC-10 at their launch in 1969, and by the early 1970s BASIC was largely universal on general-purpose mainframe computers . Even IBM eventually joined the club with the introduction of VS-BASIC in 1973. Although time-sharing services with BASIC were successful for a time,

11844-533: The enemy without damage. The player's connection is not the only factor; some servers are slower than others. A server that is geographically closer to the player's connection will often provide a lower ping. Data packets travel faster to a location that is closer to them. How far the device is from an internet connection ( router ) can also affect latency. Asymmetrical multiplayer is a type of gameplay in which players can have significantly different roles or abilities from each other – enough to provide

11985-541: The explosive growth of the microcomputer era. When IBM was designing the IBM PC , they followed the paradigm of existing home computers in having a built-in BASIC interpreter. They sourced this from Microsoft – IBM Cassette BASIC – but Microsoft also produced several other versions of BASIC for MS-DOS / PC DOS including IBM Disk BASIC (BASIC D), IBM BASICA (BASIC A), GW-BASIC (a BASICA-compatible version that did not need IBM's ROM) and QBasic , all typically bundled with

12126-431: The fifth magnitude , displayed at their relative brightness. The program was called "Expensive Planetarium"—referring to the high price of the PDP-1 computer compared to an analog planetarium, as part of the series of "expensive" programs like Piner's Expensive Typewriter —and was quickly incorporated into the game in March by Russell, who served as the collator of the primary version of the game. The initial version of

12267-488: The final version 6.0 of the original Visual Basic ended on March 31, 2005, followed by extended support in March 2008. Owing to its persistent remaining popularity, third-party attempts to further support it exist. On February 2, 2017, Microsoft announced that development on VB.NET would no longer be in parallel with that of C#, and on March 11, 2020, it was announced that evolution of the VB.NET language had also concluded. Even so,

12408-406: The first microcomputers in the mid-1970s was the start of explosive growth for BASIC. It had the advantage that it was fairly well known to the young designers and computer hobbyists who took an interest in microcomputers, many of whom had seen BASIC on minis or mainframes. Despite Dijkstra 's famous judgement in 1975, "It is practically impossible to teach good programming to students that have had

12549-602: The first commercial arcade video games , Galaxy Game and Computer Space (both from 1971), and later games such as Asteroids (1979). In 2007, Spacewar! was named to a list of the ten most important video games in history, which formed the start of the game canon at the Library of Congress , and in 2018 it was inducted into the World Video Game Hall of Fame by The Strong and the International Center for

12690-464: The first few months after its installation, the PDP-1 programming community at MIT focused on simpler programs to work out how to create software for the computer. During this period, Russell visited his old friends in the community frequently and described the Spacewar! concept to them. Russell hoped someone would implement the game, but had no plans to do so himself. Other members of the community felt he

12831-489: The first two were significant, thus it was possible to inadvertently write a program with variables "LOSS" and "LOAN", which would be treated as being the same; assigning a value to "LOAN" would silently overwrite the value intended as "LOSS". Keywords could not be used in variables in many early BASICs; "SCORE" would be interpreted as "SC" OR "E", where OR was a keyword. String variables are usually distinguished in many microcomputer dialects by having $ suffixed to their name as

12972-485: The first widely available video game of any kind. Though Tuck felt that Computer Space was a poor imitation of Spacewar! and his Galaxy Game a superior adaptation, many players believed both arcade games to be upgraded variants of Spacewar! . Byte magazine published an assembly language version of Spacewar! in 1977 that ran on the Altair 8800 and other Intel 8080 -based microcomputers using an oscilloscope as

13113-406: The game also did not include the central star gravity well or the hyperspace feature; they were written by MIT graduate student and TMRC member Dan Edwards and Graetz respectively to add elements of a strategy to what initially was a shooter game of pure reflexes. Russell had previously wanted to add gravity, but was unable to get the program to perform the calculations fast enough; Edwards optimized

13254-422: The game experience to give one player an advantage over others, such as using an " aimbot " – a program which automatically locks the player's crosshairs onto a target – in shooting games. This is also known as "hacking" or "glitching" ("glitching" refers to using a glitch , or a mistake in the code of a game, whereas "hacking" is manipulating the code of a game). Cheating in video games

13395-429: The game to other universities and institutions with a PDP-1 computer. As a result, Spacewar! was perhaps the first video game to be available outside a single research institute. Over the next decade, programmers at these other institutions began coding their own variants, including features such as allowing more ships and players at once, replacing the hyperspace feature with a cloaking device , space mines, and even

13536-578: The game was well known enough in the programming community that Rolling Stone sponsored the "Intergalactic Spacewar! Olympics". The event was held on October 19, 1972, at the Stanford Artificial Intelligence Laboratory using a variant of Spacewar! on a combined PDP-6/PDP-10 that supported five players, and was the first ever video game tournament, with an account published in the December 7, 1972 issue of Rolling Stone . In

13677-494: The game, to counter "Space War Elbow" from sitting hunched over the mainframe toggles. The game was a multiplayer-only game because the computer had no resources left over to handle controlling the other ship. Similarly, other proposed additions to the game such as a more refined explosion display upon the destruction of a spaceship and having the torpedoes also be affected by gravity had to be abandoned as there were not enough computer resources to handle them while smoothly running

13818-469: The game. One feature, having the speed and direction of torpedoes differ slightly with each shot, was added and then removed by Russell after player complaints. With the added features and changes in place, Russell and the other programmers shifted focus from developing the game to preparing to show it off to others such as at the MIT Science Open House at the end of April 1962. The group added

13959-639: The graphical display and a lookup table to approximate the calculations for orbits, as well as a three-dimensional variant in 1979 written in Tiny BASIC . More modern recreations of the game for computers have been made as well. An emulated version of the original game, made publicly available by Martin Graetz and running in a JavaScript PDP-1 emulator , was made available to play on the internet in 2012. The Analogue Pocket handheld console added support for running Spacewar! on an emulated PDP-1 in 2022. The only working PDP-1s that are known to exist are kept in

14100-413: The gravitational pull of the star. The ships have a limited number of torpedoes and supply of fuel, which is used when the player fires the ship's thrusters. Torpedoes are fired one at a time by flipping a toggle switch on the computer or pressing a button on the control pad, and there is a cooldown period between launches. The ships remain in motion even when the player is not accelerating, and rotating

14241-869: The language was still supported. Many other BASIC dialects have also sprung up since 1990, including the open source QB64 and FreeBASIC , inspired by QBasic, and the Visual Basic-styled RapidQ , HBasic , Basic For Qt and Gambas . Modern commercial incarnations include PureBasic , PowerBASIC , Xojo , Monkey X and True BASIC (the direct successor to Dartmouth BASIC from a company controlled by Kurtz). Several web-based simple BASIC interpreters also now exist, including Microsoft's Small Basic and Google 's wwwBASIC. A number of compilers also exist that convert BASIC into JavaScript . such as NS Basic . Building from earlier efforts such as Mobile Basic , many dialects are now available for smartphones and tablets. On game consoles, an application for

14382-498: The language. How to design and implement a stripped-down version of an interpreter for the BASIC language was covered in articles by Allison in the first three quarterly issues of the People's Computer Company newsletter published in 1975 and implementations with source code published in Dr. Dobb's Journal of Tiny BASIC Calisthenics & Orthodontia: Running Light Without Overbyte . This led to

14523-509: The language. In the following years, as other dialects of BASIC appeared, Kemeny and Kurtz's original BASIC dialect became known as Dartmouth BASIC . New Hampshire recognized the accomplishment in 2019 when it erected a highway historical marker in Hanover describing the creation of "the first user-friendly programming language". The emergence of BASIC took place as part of a wider movement toward time-sharing systems. First conceptualized during

14664-563: The late 1950s, the idea became so dominant in the computer industry by the early 1960s that its proponents were speaking of a future in which users would "buy time on the computer much the same way that the average household buys power and water from utility companies". General Electric, having worked on the Dartmouth project, wrote their own underlying operating system and launched an online time-sharing system known as Mark I. It featured BASIC as one of its primary selling points. Other companies in

14805-403: The latter half of the 1980s, users were increasingly using pre-made applications written by others rather than learning programming themselves; while professional programmers now had a wide range of more advanced languages available on small computers. C and later C++ became the languages of choice for professional "shrink wrap" application development. A niche that BASIC continued to fill

14946-581: The latter was an early first-person shooter . Other early video games included turn-based multiplayer modes, popular in tabletop arcade machines . In such games, play is alternated at some point (often after the loss of a life ). All players' scores are often displayed onscreen so players can see their relative standing. Danielle Bunten Berry created some of the first multiplayer video games, such as her debut, Wheeler Dealers (1978) and her most notable work, M.U.L.E. (1983). Gauntlet (1985) and Quartet (1986) introduced co-operative 4-player gaming to

15087-524: The linker to make EXE files, is present in the Windows NT and DOS- Windows 95 streams of operating systems and can be obtained for more recent releases like Windows 7 which do not have them. Prior to DOS 5, the Basic interpreter was GW-Basic . QuickBasic is part of a series of three languages issued by Microsoft for the home and office power user and small-scale professional development; QuickC and QuickPascal are

15228-685: The machine. In addition they produced the Microsoft BASIC Compiler aimed at professional programmers. Turbo Pascal -publisher Borland published Turbo Basic 1.0 in 1985 (successor versions are still being marketed under the name PowerBASIC ). On Unix-like systems, specialized implementations were created such as XBasic and X11-Basic . XBasic was ported to Microsoft Windows as XBLite , and cross-platform variants such as SmallBasic , yabasic , Bywater BASIC , nuBasic , MyBasic , Logic Basic , Liberty BASIC , and wxBasic emerged. FutureBASIC and Chipmunk Basic meanwhile targeted

15369-459: The new computer's capabilities in a compelling way. Three of them— Steve Russell , then an employee at Harvard University and a former research assistant at MIT; Martin Graetz, a research assistant and former student at MIT; and Wayne Wiitanen, a research assistant at Harvard and former employee and student at MIT—came up with the idea for Spacewar! . They referred to their collaboration as the "Hingham Institute" as Graetz and Wiitanen were living in

15510-580: The original 101 BASIC games converted into the Microsoft dialect and published it from Creative Computing as BASIC Computer Games . This book, and its sequels, provided hundreds of ready-to-go programs that could be easily converted to practically any BASIC-running platform. The book reached the stores in 1978, just as the home computer market was starting off, and it became the first million-selling computer book. Later packages, such as Learn to Program BASIC would also have gaming as an introductory focus. On

15651-446: The other two. For Windows 95 and 98, which do not have QBasic installed by default, they can be copied from the installation disc, which will have a set of directories for old and optional software; other missing commands like Exe2Bin and others are in these same directories. The various Microsoft, Lotus, and Corel office suites and related products are programmable with Visual Basic in one form or another, including LotusScript , which

15792-427: The player can engage a hyperspace feature to move to a new and random location on the screen, though in some versions each use has an increasing chance of destroying the ship instead. The game was initially controlled with switches on the PDP-1, though Bob Saunders built an early gamepad to reduce the difficulty and awkwardness of controlling the game. Spacewar! is one of the most important and influential games in

15933-585: The power of the computer they ran on and as entertainment products; these were generally created by undergraduate and graduate students and university employees, such as at the Massachusetts Institute of Technology (MIT), where staff and students were allowed on occasion to develop programs for the TX-0 experimental computer. These interactive graphical games were created by a community of programmers, many of them students and university employees affiliated with

16074-534: The programming community was too small to support any commercial industry. It spread initially both by people bringing copies of the code to other installations as well as by programmers recreating the game with their own code. Early installations included the PDP-1 at Bolt, Beranek, & Newman , which also recreated the gamepads; an installation by Russell on a PDP-1 at the Artificial Intelligence Laboratory of Stanford University in 1963; and

16215-470: The programming language, Kemeny and Kurtz developed the Dartmouth Time-Sharing System (DTSS), which allowed multiple users to edit and run BASIC programs simultaneously on remote terminals. This general model became popular on minicomputer systems like the PDP-11 and Data General Nova in the late 1960s and early 1970s. Hewlett-Packard produced an entire computer line for this method of operation, introducing

16356-426: The release of VB version 3.0, which is widely considered the first relatively stable version. Microsoft also spun it off as Visual Basic for Applications and Embedded Visual Basic . While many advanced programmers still scoffed at its use, VB met the needs of small businesses efficiently as by that time, computers running Windows 3.1 had become fast enough that many business-related processes could be completed "in

16497-440: The same power as C# and Java but with syntax that reflects the original Basic language, and also features some cross-platform capability through implementations such as Mono-Basic . The IDE , with its event-driven GUI builder , was also influential on other rapid application development tools, most notably Borland Software 's Delphi for Object Pascal and its own descendants such as Lazarus . Mainstream support for

16638-528: The same room using splitscreen . Some of the earliest video games were two-player games, including early sports games (such as 1958's Tennis For Two and 1972's Pong ), early shooter games such as Spacewar! (1962) and early racing video games such as Astro Race (1973). The first examples of multiplayer real-time games were developed on the PLATO system about 1973. Multi-user games developed on this system included 1973's Empire and 1974's Spasim ;

16779-416: The ship exploding with each use. Player controls include clockwise and counterclockwise rotation, forward thrust, firing torpedoes, and hyperspace. Initially, these were controlled using the front-panel test switches on the PDP-1 minicomputer, with four switches for each player, but these proved to be awkward to use and wore out quickly under normal gameplay, as well as causing players to accidentally flip

16920-409: The ships does not change the direction of their motion, though the ships can rotate at a constant rate without inertia . Each player controls one of the ships and must attempt to shoot down the other ship while avoiding a collision with the star or the opposing ship. Flying near the star can provide a gravity assist to the player at the risk of misjudging the trajectory and falling into the star. If

17061-524: The stories would make a good basis for the program. "His heroes had a strong tendency to get pursued by the villain across the galaxy and have to invent their way out of their problem while they were being pursued. That sort of action was the thing that suggested Spacewar! . He had some very glowing descriptions of spaceship encounters and space fleet maneuvers." Other influences cited by fellow programmer Martin Graetz include E. E. Smith's Skylark novels and Japanese pulp fiction tokusatsu movies . For

17202-452: The third of the default engines along with VBScript, JScript, and the numerous proprietary or open source engines which can be installed like PerlScript , a couple of Rexx-based engines, Python, Ruby, Tcl, Delphi, XLNT, PHP, and others; meaning that the two versions of Basic can be used along with the other mentioned languages, as well as LotusScript, in a WSF file, through the component object model, and other WSH and VBA constructions. VBScript

17343-685: The widespread availability of the Internet which allowed players to play against each other simultaneously, but remains an option in many strategy-related games, such as the Civilization series . Coordination of turns are subsequently managed by one computer or a centralized server. Further, many mobile games are based on sporadic play and use social interactions with other players , lacking direct player versus player game modes but allowing players to influence other players' games, coordinated through central game servers, another facet of asynchronous play. Online cheating (in gaming) usually refers to modifying

17484-412: The widespread success predicted earlier was not to be. The emergence of minicomputers during the same period, and especially low-cost microcomputers in the mid-1970s, allowed anyone to purchase and run their own systems rather than buy online time which was typically billed at dollars per minute. BASIC, by its very nature of being small, was naturally suited to porting to the minicomputer market, which

17625-466: Was HP Time-Shared BASIC , which, like the original Dartmouth system, used two computers working together to implement a time-sharing system. The first, a low-end machine in the HP 2100 series, was used to control user input and save and load their programs to tape or disk. The other, a high-end version of the same underlying machine, ran the programs and generated output. For a cost of about $ 100,000, one could own

17766-407: Was a simple matter to type in the code from the magazine and execute the program. Different magazines were published featuring programs for specific computers, though some BASIC programs were considered universal and could be used in machines running any variant of BASIC (sometimes with minor adaptations). Many books of type-in programs were also available, and in particular, Ahl published versions of

17907-515: Was as simple as that." Kemeny and Kurtz had made two previous experiments with simplified languages, DARSIMCO (Dartmouth Simplified Code) and DOPE (Dartmouth Oversimplified Programming Experiment) . These did not progress past a single freshman class. New experiments using Fortran and ALGOL followed, but Kurtz concluded these languages were too tricky for what they desired. As Kurtz noted, Fortran had numerous oddly formed commands, notably an "almost impossible-to-memorize convention for specifying

18048-714: Was available for almost any system of the era, and became the de facto programming language for home computer systems that emerged in the late 1970s. These PCs almost always had a BASIC interpreter installed by default, often in the machine's firmware or sometimes on a ROM cartridge. BASIC declined in popularity in the 1990s, as more powerful microcomputers came to market and programming languages with advanced features (such as Pascal and C ) became tenable on such computers. By then, most nontechnical personal computer users relied on pre-written applications rather than writing their own programs. In 1991, Microsoft released Visual Basic , combining an updated version of BASIC with

18189-757: Was co-written by Bill Gates , Paul Allen and Monte Davidoff for their newly formed company, Micro-Soft. This was released by MITS in punch tape format for the Altair 8800 shortly after the machine itself, immediately cementing BASIC as the primary language of early microcomputers. Members of the Homebrew Computer Club began circulating copies of the program, causing Gates to write his Open Letter to Hobbyists , complaining about this early example of software piracy . Partially in response to Gates's letter, and partially to make an even smaller BASIC that would run usefully on 4 KB machines, Bob Albrecht urged Dennis Allison to write their own variation of

18330-542: Was due to their work with RAND Corporation , who had purchased a PDP-6 to run their JOSS language, which was conceptually very similar to BASIC. This led DEC to introduce a smaller, cleaned up version of JOSS known as FOCAL , which they heavily promoted in the late 1960s. However, with timesharing systems widely offering BASIC, and all of their competition in the minicomputer space doing the same, DEC's customers were clamoring for BASIC. After management repeatedly ignored their pleas, David H. Ahl took it upon himself to buy

18471-415: Was emerging at the same time as the time-sharing services. These machines had small main memory , perhaps as little as 4 KB in modern terminology, and lacked high-performance storage like hard drives that make compilers practical. On these systems, BASIC was normally implemented as an interpreter rather than a compiler due to its lower requirement for working memory. A particularly important example

18612-418: Was extremely popular in the small programming community in the 1960s and was widely recreated on other minicomputer and mainframe computers of the time before migrating to early microcomputer systems in the 1970s. Just as it was during development, the game was in the public domain and the code was available to anyone with access to it or who contacted Russell; no attempt was made to sell it commercially, as

18753-499: Was for hobbyist video game development , as game creation systems and readily available game engines were still in their infancy. The Atari ST had STOS BASIC while the Amiga had AMOS BASIC for this purpose. Microsoft first exhibited BASIC for game development with DONKEY.BAS for GW-BASIC , and later GORILLA.BAS and NIBBLES.BAS for QuickBASIC . QBasic maintained an active game development community, which helped later spawn

18894-419: Was heavily patterned on FORTRAN II; statements were one-to-a-line, numbers were used to indicate the target of loops and branches, and many of the commands were similar or identical to Fortran. However, the syntax was changed wherever it could be improved. For instance, the difficult to remember DO loop was replaced by the much easier to remember FOR I = 1 TO 10 STEP 2 , and the line number used in

19035-558: Was installed in the " kludge room" on the 2nd floor of Building 26, the location of the MIT Electrical Engineering Department. The PDP-1 was to complement the older TX-0, and like it had a punched tape reader and writer, and additionally accepted input from a panel of switches and could output to a cathode-ray tube (CRT) display. Over the summer before its arrival a group of students and university employees had been pondering ideas for programs that would demonstrate

19176-441: Was named to a list of the ten most important video games in history, the so-called game canon , which were proposed to be archived in the Library of Congress . The Library of Congress took up this video game preservation proposal and began with the games from this list. In 2018, it was inducted into the World Video Game Hall of Fame by The Strong and the International Center for the History of Electronic Games . Also in 2018,

19317-453: Was only after 1967 that computers hooked up to monitors or terminals capable of playing Spacewar! began to proliferate, allowing the game to reach a wider audience and influence later video game designers—by 1971, it is estimated that there were over 1000 computers with monitors, rather than a few dozen. It is around this time that the majority of the game variants were created for various computer systems, such as later PDP systems, and in 1972

19458-450: Was reportedly used as a smoke test by DEC technicians on new PDP-1 systems before shipping because it was the only available program that exercised every aspect of the hardware. Although the game was widespread for the era, it was still very limited in its direct reach: while less expensive than most mainframe computers, the PDP-1 was priced at US$ 120,000 (equivalent to about $ 1,209,000 in 2023) and only 53 were ever sold, most without

19599-437: Was such that textbooks once included simple "Try It In BASIC" exercises that encouraged students to experiment with mathematical and computational concepts on classroom or home computers. Popular computer magazines of the day typically included type-in programs . Futurist and sci-fi writer David Brin mourned the loss of ubiquitous BASIC in a 2006 Salon article as have others who first used computers during this era. In turn,

19740-439: Was the logical choice to create the game, however, and began pressuring him to program it. In response, Russell began providing various excuses as to why he could not do so. One of these was the lack of a trigonometric function routine needed to calculate the trajectories of the spacecraft. This prompted Alan Kotok of the TMRC to call DEC, who informed him that they had such a routine already written. Kotok drove to DEC to pick up

19881-531: Was written for the newly installed DEC PDP-1 minicomputer at the Massachusetts Institute of Technology . After its initial creation, Spacewar! was expanded further by other students and employees of universities in the area, including Dan Edwards and Peter Samson . It was also spread to many of the few dozen installations of the PDP-1 computer, making Spacewar! the first known video game to be played at multiple computer installations. The game features two spaceships , "the needle" and "the wedge", engaged in
