In 1982, Bally merged its pinball division with Midway to form the Bally/Midway Manufacturing division. Three games released that year, including Satan’s Hollow, were the first to feature the Bally/Midway brand. From the late 1970s through the late 1980s, Midway was the leading producer of arcade video games in the United States.
The Bally/Midway division of Bally was purchased and reincorporated in 1988 by the arcade and pinball game company Williams Electronics Games through its holding company WMS Industries Inc. Midway moved its headquarters from Franklin Park, Illinois to Williams’s then-headquarters in Chicago, and WMS reincorporated Midway as a Delaware corporation. Although WMS retained many of Midway’s R&D employees, only two game designers were retained: Rampage designers Brian Colin and Jeff Nauman. WMS obtained the right from Bally to use the “Bally” brand for its pinball games since Bally had completely left the arcade/pinball industry to concentrate on casinos and slot machines.
Under WMS ownership, Midway initially continued to produce arcade games under the Bally/Midway label, while producing pinball machines under the “Bally” brand. In 1991, however, Midway absorbed Williams’ video game division and started making arcade games under its own name again, without the “Bally” part. In 1992, the company’s The Addams Family machine became the best selling pinball game of all time.[12] In 1996, WMS purchased Time-Warner Interactive, which included Atari Games, a part of the former giant Atari Inc.. Also in 1996, Midway changed its original corporate name, Midway Manufacturing, to Midway Games Inc., due to its entrance in the home console market. The original arcade division of the company became Midway Amusement Games and the newly created home division was named Midway Home Entertainment.[15]
