Early history of video games
That same year saw the release of the Magnavox Odyssey, the first home video game console which could be connected to a television set. The inventor, Ralph H. Baer, had initially had the idea in 1951 to make an interactive game on a television set. Unable to do so with the technological constraints at the time, he began work on a device that would attach to a television set and display games in 1966, and the "Brown Box", the last prototype of seven, was licensed to Magnavox to adapt and produce. They announced the console in May 1972, and it went on sale that September. The console and its games featured numerous innovations beyond being the first video game device for home consumers: it was the first game to use a raster-scan video display, or television set, directly displayed via modification of a video signal; it was also the first video gaming device to be displayed in a television commercial. It sold for US$100 and shipped with several games, including "Table tennis", which Bushnell had seen a demo of and which "Pong" had been based on. The Odyssey sold over 100,000 units in 1972, and more than 350,000 by the end of 1975, buoyed by the popularity of the table tennis game, in turn driven by the success of "Pong". "Pong" and the Odyssey kicked off a new era of video gaming, with numerous other competitors starting up in the video game industry as it grew in popularity.
History of video games
The first games known to incorporate a monitor were two research projects completed in 1952, a checkers program by Christopher Strachey on the Ferranti Mark 1 and a tic-tac-toe program called "OXO" by Alexander Douglas on the EDSAC. Both of these programs used a relatively static display to track the current state of the game board. The first known game incorporating graphics that updated in real time was a billiards game programmed by William Brown and Ted Lewis specifically for a demonstration of the MIDSAC computer at the University of Michigan in 1954.
Perhaps the first game created solely for entertainment rather than to demonstrate the power of some technology, train personnel, or aid in research was "Tennis for Two", designed by William Higinbotham and built by Robert Dvorak at the Brookhaven National Laboratory in 1958. Designed to entertain the general public at Brookhaven's annual series of open houses, the game was deployed on an analog computer with graphics displayed on an oscilloscope and was dismantled in 1959. Higinbotham never considered adapting the successful game into a commercial product, which would have been impractical with the technology of the time. Ultimately, the widespread adoption of computers to play games would have to wait for the machines to spread from serious academics to their students on U.S. college campuses.
