Midway Games is an American company that was formerly a major video game publisher and developer. Following a bankruptcy filing in 2009, it is no longer active and is in the process of liquidating all of its assets. Midway's titles included Mortal Kombat, Ms. Pac-Man, Spy Hunter, Tron, Rampage, the Cruis'n series, NFL Blitz and NBA Jam. Midway also acquired the rights to video games that were originally developed by Williams Electronics and Atari Games, such as Defender, Joust, Robotron 2084, Gauntlet and the Rush series. The company's predecessor was founded in 1958 as Midway Manufacturing, an amusement game manufacturer. In 1973 it moved into the interactive entertainment industry, developing and publishing arcade video games. The company scored its first mainstream hit with the U.S. distribution of Space Invaders in 1978. Midway was purchased and re-incorporated in 1988 by WMS Industries Inc. After many years as a leader in the arcade segment, Midway moved into the growing home video game market beginning in 1996, the same year that it made its initial public offering of stock. In 1998, WMS spun off its remaining shares of Midway. Midway was ranked as the fourth largest-selling video game publisher in 2000.
