Bertie the Brain is one of the first games developed in the early history of video games. It was built in Toronto by Josef Kates for the 1950 Canadian National Exhibition. The four meter (13 foot) tall computer allowed exhibition attendees to play a game of tic-tac-toe against an artificial intelligence. The player entered a move on a keypad in the form of a three-by-three grid, and the game played out on a grid of lights overhead. The machine had an adjustable difficulty level. After two weeks on display by Rogers Majestic, the machine was disassembled at the end of the exhibition and largely forgotten as a curiosity.

Kates built the game to showcase his additron tube, a miniature version of the vacuum tube, though the transistor overtook it in computer development shortly thereafter. Patent issues prevented the additron tube from being used in computers besides Bertie before it was no longer useful. Bertie the Brain is a candidate for the first video game, as it was potentially the first computer game to have any sort of visual display of the game. It appeared only three years after the 1947 invention of the cathode-ray tube amusement device, the earliest known interactive electronic game to use an electronic display. Bertie's use of light bulbs rather than a screen with real-time visual graphics, however, much less moving graphics, does not meet some definitions of a video game.

History

Bertie the Brain was a video game version of tic-tac-toe, built by Dr. Josef Kates for the 1950 Canadian National Exhibition. [1] Kates had previously worked at Rogers Majestic designing and building radar tubes during World War II, then after the war pursued graduate studies in the computing center at the University of Toronto while continuing to work at Rogers Majestic. [2] While there, he helped build the University of Toronto Electronic Computer (UTEC), one of the first working computers in the world. He also designed his own miniature version of the vacuum tube, called the additron tube, which he registered with the Radio Electronics Television Manufacturers' Association on 20 March 1951 as type 6047. [2] [3] [4] [5]

After filing for a patent for the additron tube, Rogers Majestic pushed Kates to create a device to showcase the tube to potential buyers. Kates designed a specialized computer incorporating the technology and built it with the assistance of engineers from Rogers Majestic. [2] [6] The large, four meter (13 foot) tall metal computer could only play tic-tac-toe and was installed in the Engineering Building at the Canadian National Exhibition from 25 August–9 September 1950. [2] [7]

The additron-based computer, labeled as "Bertie the Brain" and subtitled "The Electronic Wonder by Rogers Majestic", was a success at the two-week exhibition, with attendees lining up to play it. Kates stayed by the machine when possible, adjusting the difficulty up or down for adults and children. Comedian Danny Kaye was photographed defeating the machine (after several attempts) for Life magazine. [2]

Gameplay

Bertie the Brain was a game of tic-tac-toe in which the player would select the position for their next move from a grid of nine lit buttons on a raised panel. The moves would appear on a grid of nine large squares set vertically on the machine as well as on the buttons, with either an X- or O-shaped light turning on in the corresponding space. The computer would make its move shortly after. A pair of signs to the right of the playfield, alternately lit up with "Electronic Brain" and an X or "Human Brain" and an O, marked which player's turn it was, and would light up along with "Win" when a player had won. Bertie could be set to several difficulty levels. [2] The computer responded almost instantly to the player's moves and at the highest difficulty level was designed to be unbeatable. [6]

Legacy

After the exhibition, Bertie was dismantled and "largely forgotten" as a novelty. Kates has said that he was working on so many projects at the same time that he had no energy to spare for preserving it, despite its significance. [2] Despite being the first implemented computer game—preceded only by theorized chess programs—and featured in an unpublished Life magazine article, the game was largely forgotten, even by video game history books. [6] Bertie's primary purpose, to promote the additron tube, went unfulfilled, as it was the only completed application of the technology. By the time Rogers Majestic pushed Kates to develop a working model for the Exhibition, he had been working on the tubes for a year, developing several revisions, and the University of Toronto team felt that the development was too slow to attempt to integrate them into the UTEC. [8]

Although other firms expressed interest to Kates and Rogers Majestic in using the tubes, issues with acquiring patents prevented him, Rogers Majestic, or the University of Toronto from patenting the tubes anywhere outside Canada until 1955, and the patent application was not accepted in the United States until March 1957, six years after filing. [8] [9] By then, research and use of vacuum tubes was heavily waning in the face of the rise of the superior transistor, preventing any re-visitation of Bertie or similar machines. Kates went on to a distinguished career in Canadian engineering, but did not return to working on vacuum tubes or computer games. [8]

Bertie was created only three years after the 1947 invention of the cathode-ray tube amusement device, the earliest known interactive electronic game, and while non-visual games had been developed for research computers such as Alan Turing and Dietrich Prinz's chess program for the Ferranti Mark 1 at the University of Manchester, Bertie was the first computer-based game to feature a visual display of any sort. [2] [10] [11] Bertie is considered under some definitions in contention for the title of the first video game. While definitions vary, the prior cathode-ray tube amusement device was a purely analog electrical game, and while Bertie did not feature an electronic screen it did run on a computer. [12] Another special-purpose computer-based game, Nimrod , was built in 1951, while the software-based tic-tac-toe game OXO and a draughts program by Christopher Strachey were in 1952 the first computer games to display visuals on an electronic screen rather than light bulbs.

<span class="mw-page-title-main">Cathode-ray tube</span> Vacuum tube often used to display images

A cathode-ray tube (CRT) is a vacuum tube containing one or more electron guns, which emit electron beams that are manipulated to display images on a phosphorescent screen. The images may represent electrical waveforms on an oscilloscope, a frame of video on an analog television set (TV), digital raster graphics on a computer monitor, or other phenomena like radar targets. A CRT in a TV is commonly called a picture tube. CRTs have also been used as memory devices, in which case the screen is not intended to be visible to an observer. The term cathode ray was used to describe electron beams when they were first discovered, before it was understood that what was emitted from the cathode was a beam of electrons.

<i>Tennis for Two</i> 1958 video game

Tennis for Two is a sports video game that simulates a game of tennis, and was one of the first games developed in the early history of video games. American physicist William Higinbotham designed the game in 1958 for display at the Brookhaven National Laboratory's annual public exhibition after learning that the government research institution's Donner Model 30 analog computer could simulate trajectories with wind resistance. He designed the game within a few hours, after which he and technician Robert V. Dvorak built it over a period of three weeks. The game was displayed on an oscilloscope and played with two custom aluminum controllers. Its visuals show a representation of a tennis court viewed from the side, and players adjust the angle of their shots with a knob on their controller and try to hit the ball over the net by pressing a button.

<span class="mw-page-title-main">Nimrod (computer)</span> 1951 British computer

The Nimrod, built in the United Kingdom by Ferranti for the 1951 Festival of Britain, was an early computer custom-built to play Nim, inspired by the earlier Nimatron. The twelve-by-nine-by-five-foot (3.7-by-2.7-by-1.5-meter) computer, designed by John Makepeace Bennett and built by engineer Raymond Stuart-Williams, allowed exhibition attendees to play a game of Nim against an artificial intelligence. The player pressed buttons on a raised panel corresponding with lights on the machine to select their moves, and the Nimrod moved afterward, with its calculations represented by more lights. The speed of the Nimrod's calculations could be reduced to allow the presenter to demonstrate exactly what the computer was doing, with more lights showing the state of the calculations. The Nimrod was intended to demonstrate Ferranti's computer design and programming skills rather than to entertain, though Festival attendees were more interested in playing the game than the logic behind it. After its initial exhibition in May, the Nimrod was shown for three weeks in October 1951 at the Berlin Industrial Show before being dismantled.

Rogers Vacuum Tube Company was founded as the Standard Radio Manufacturing Corporation in 1925 by Edward Rogers (1900–1939) to sell Rogers "Batteryless" radios using vacuum tube technology. It was later renamed Rogers Majestic Corporation Limited when Rogers merged his company with Majestic Corporation of Chicago in 1928. The new company controlled Rogers Radio Tube Company and Rogers Batteryless Radio Company. Joseph Elsworth Rogers (1898–1960), brother of Edward Rogers, was an important member of the company and served as vice-president until 1939, and then as head from 1939 to 1960.

The history of video games spans a period of time between the invention of the first electronic games and today, covering many inventions and developments. Video gaming reached mainstream popularity in the 1970s and 1980s, when arcade video games, gaming consoles and home computer games were introduced to the general public. Since then, video gaming has become a popular form of entertainment and a part of modern culture in most parts of the world. The early history of video games, therefore, covers the period of time between the first interactive electronic game with an electronic display in 1947, the first true video games in the early 1950s, and the rise of early arcade video games in the 1970s. During this time there was a wide range of devices and inventions corresponding with large advances in computing technology, and the actual first video game is dependent on the definition of "video game" used.

<span class="mw-page-title-main">Cathode-ray tube amusement device</span> Earliest known interactive electronic game

The cathode-ray tube amusement device is the earliest known interactive electronic game as well as the first game to incorporate an electronic display. The device simulates an artillery shell arcing towards targets on a cathode-ray tube (CRT) screen, which is controlled by the player by adjusting knobs to change the trajectory of a CRT beam spot on the display in order to reach plastic targets overlaid on the screen. Thomas T. Goldsmith Jr. and Estle Ray Mann constructed the game from analog electronics and filed for a patent in 1947, which was issued the following year. The gaming device was never manufactured or marketed to the public, so it had no effect on the future video game industry. Under many definitions, the device is not considered a video game, as while it had an electronic display it did not run on a computing device. Therefore, despite its relevance to the early history of video games, it is not generally considered a candidate for the title of the first video game.

<span class="mw-page-title-main">Ultimate tic-tac-toe</span> Variant of tic-tac-toe game

Ultimate tic-tac-toe is a board game composed of nine tic-tac-toe boards arranged in a 3 × 3 grid. Players take turns playing on the smaller tic-tac-toe boards until one of them wins on the larger board. Compared to traditional tic-tac-toe, strategy in this game is conceptually more difficult and has proven more challenging for computers.

<span class="mw-page-title-main">Tic-tac-toe variants</span>

Tic-tac-toe is an instance of an m,n,k-game, where two players alternate taking turns on an m×n board until one of them gets k in a row. Harary's generalized tic-tac-toe is an even broader generalization. The game can also be generalized as a nd game. The game can be generalised even further from the above variants by playing on an arbitrary hypergraph where rows are hyperedges and cells are vertices.
