of an electronic device that could be connected to a standard television to play games. With Sanders' permission, he brought this design to practice, creating the prototype "Brown Box" which was able to play a limited number of games, including a version of table tennis and a simple light gun game. Sanders patented the unit and licensed the patents to Magnavox, where it was manufactured as the first home video game console, the Magnavox Odyssey, in 1972. Bushnell, after seeing the Odyssey and its table tennis game, believed he could make something better. He and Dabney formed Atari, Inc., and with Allan Alcorn, created their second arcade game Pong, first released in 1972 which was more successful than Computer Space. Atari released a Pong console of its own design through Sears in 1975. Handheld consoles The origins of handheld game consoles are found in handheld and tabletop electronic game devices of the 1970s and early 1980s. These electronic devices are capable of playing only pre-defined built-in games, they fit in the palm of the hand or on a tabletop, and they may make use of a variety of video display technologies such as LED, VFD, or LCD. Handheld electronic games, in turn, were derived from the emerging optoelectronic-display-driven calculator market of the early 1970s. The first such handheld electronic game was released by Mattel in 1977, where Michael Katz, Mattel's new product category marketing director, told the engineers in the electronics group to design a game the size of a calculator, using LED technology." This effort lead to the 1977 games Auto Race and Football. The two games were so successful that according to Katz, "these simple electronic handheld games turned into a '$400 million category.'" Another Ralph Baer invention, Simon, published by Milton Bradley in 1978, followed, which further popularized such electronic games and remained an enduring property by Milton Bradley (later Hasbro) that brought a number of copycats to the market. Soon, other manufacturers including Coleco, Parker Brothers, Entex, and Bandai began following up with their own tabletop and handheld electronic games. The transition from handheld electronic games to handheld video games came with the introduction of LCD screens which today have the capability to present a large number of pixels across a display, approaching the video format used by home consoles, and giving the unit more flexibility in playing a range of games.
