Gremlin Industries was an American arcade game developer and manufacturer who manufactured wall games in the early 1970s before switching to video games starting 1976. In 1978, they were purchased by Sega, and started releasing games with joint branding, first as Gremlin/Sega, then as Sega/Gremlin.

Sega/Gremlin changed their name to Sega Electronics in late 1982 (according to chairman David Rosen, the combined name was "a bit awkward"). Around which time they also started producing games for home systems, attempting to bring Paramount brands to home consoles (Star Trek: Strategic Operations Simulator and Buck Rogers: Planet of Zoom being the two surviving examples, though many more were planned).

Sega Electronics was sold to Bally Midway after the summer of 1983 for an undisclosed price. Home video games would continue to be sold under the Sega brand (including some of Midway's back catalogue, such as Tapper and Spy Hunter), but all arcade efforts would be badged as Bally Midway games. This would include games made by Sega in Japan for a short period (though Sega's Japanese business was otherwise unaffected by the sale).
