In the history of video games, the first generation era refers to the video games, video game consoles, and handheld video game consoles available from 1972 to 1983. Notable consoles of the first generation include the Odyssey series (excluding the Magnavox Odyssey 2), the Atari Home Pong, the Coleco Telstar series and the Color TV-Game series. The generation ended with the Computer TV-Game in 1980, but many manufacturers had left the market prior due to the market decline in the year of 1977 and the start of the second generation of video game consoles. Most of the games developed during this generation were hard-wired into the consoles and unlike later generations, most were not contained on removable media that the user could switch between. Consoles often came with accessories and cartridges that could alter the way the game played to enhance the gameplay experience as graphical capabilities consisted of simple geometry such as dots, lines or blocks that would occupy only a single screen. First generation consoles were not capable of displaying more than two colours until later in the generation, and audio capabilities were limited with some consoles having no sound at all. In 1972, two major developments influenced the future of the home video game market. In June, Nolan Bushnell and Ted Dabney founded Atari, which would go on to be one of the most well-known video game companies and play a vital role in the early generations of consoles. In September, Magnavox, an established electronics company, released the Odyssey. While highly limited in its capabilities compared to future consoles and a commercial failure, the Odyssey introduced features that became standards in the industry including removable cartridges and multiple detached controllers for two players. Inspired by the Odyssey's ping-pong game, Atari would soon go on to market the game Pong in both arcade and home versions; Nintendo, a well-established Japanese company that made a number of different products, entered the video game console market for the first time in 1977 with its Color TV-Game series.

Baer did not pursue the idea, but it returned to him in August 1966 when he was the Chief Engineer and manager of the Equipment Design Division at Sanders Associates. By December 1966, he and a
