WMS Industries

WMS Industries, Inc. is an American electronic gaming and amusement company with development facilities and main headquarters in Las Vegas, Nevada. The company's main operating subsidiaries are WMS Gaming and Williams Interactive. WMS traces its roots to 1943, to the Williams Manufacturing Company, founded by Harry E. Williams. However, the company that is known today as WMS Industries was formally founded in 1974 as Williams Electronics, Inc. In 2013, it became a wholly owned subsidiary of Scientific Games.

Williams initially was a manufacturer of pinball machines. In 1964 Williams was acquired by jukebox manufacturer Seeburg Corp. and reorganized as Williams Electronics Manufacturing Division. In 1973, the company branched out into the coin-operated arcade video game market with its Pong clone Paddle Ball. In 1974, Williams Electronics, Inc. was incorporated in Delaware as a wholly owned subsidiary of Seeburg and replaced the previous entity. In 1987, Williams changed its parent name to WMS Industries, Inc. when it made its public offering. WMS is a shortening of Williams, which it also selected for its NYSE ticker symbol. In 1988, it acquired competitor Bally/Midway, which it spun off in 1998, together with its video game business. It closed its pinball division in 1999.
