WMS

Wms Industries Inc.

A maker of casino slot machines and gaming content, best known for its long-running line of Monopoly-themed video slots that have been a fixture on casino floors since 1998. The company began in 1943 as Williams Manufacturing, a Chicago pinball maker founded by Harry E. Williams, and later produced arcade classics like Defender and Joust before pivoting to casino gaming; it took the name WMS Industries when it went public in 1987, with "WMS" short for "Williams."
