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.
Strategy video game
The origin of strategy video games is rooted in traditional tabletop strategy games like Chess and Go, as well as board and miniature wargaming. The first console strategy game was a "Risk"-like game called "Invasion," released in 1972 for the Magnavox Odyssey. Strategic Simulations (SSI)'s "Computer Bismarck", released in 1980, was the first historical computer wargame. Companies such as SSI, Avalon Hill, MicroProse, and Strategic Studies Group released many strategy titles throughout the 1980s. "Reach for the Stars" from 1983 was one of the first 4X strategy games, which expanded upon the relationship between economic growth, technological progress, and conquest. That same year, "Nobunaga's Ambition" was a conquest-oriented grand strategy wargame with historical simulation elements. "The Lords of Midnight" combined elements of adventure, strategy and wargames, and won the Crash magazine award for Best Adventure game of 1984, as well as Best Strategy Game of the Year at the Golden Joystick Awards
