Did Sega and Timex Sinclair both develop electronics?
Sega Sega Games Co., Ltd. (Japanese: 株式会社セガゲームス , Hepburn: Kabushiki gaisha Sega gēmusu ) , originally short for Service Games and officially styled as SEGA, is a Japanese multinational video game developer and publisher headquartered in Tokyo, Japan, with offices around the world. Sega developed and manufactured numerous home video game consoles from 1983 to 2001, but after financial losses incurred from its Dreamcast console, the company restructured to focus on providing software as a third-party developer. Sega remains the world's most prolific arcade producer, with over 500 games in over 70 franchises on more than 20 different arcade system boards since 1981.
Cinematronics Cinematronics Incorporated was a pioneering arcade game developer that had its heyday in the era of vector display games. While other companies released games based on raster displays, early in their history, Cinematronics and Atari released vector-display games, which offered a distinctive look and a greater graphic capability (at the time), at the cost of being only black and white (initially).
