Bally Technologies, Inc. is a manufacturer of slot machines and other gaming technology based in Enterprise, Nevada. It is owned by Scientific Games Corporation.
The company was founded in 1968 as Advanced Patent Technology. It eventually changed its name to Alliance Gaming and acquired, in 1996, Bally Gaming International, a former division of Bally Manufacturing. In 2006, the entire company adopted the Bally name. Scientific Games acquired the company in 2014.
Advanced Patent Technology was founded in 1968 by Jack Solomon and Alvin Snapper, entrepreneurs who held patents in fields including medicine, optics, and electronics. The company's stock was publicly offered the next year. Its first 12 years were spent in the development stage. It boasted a portfolio of over 80 patents, but generated considerable publicity for five in particular: an ultrasonic fluidic fuel system for combustion engines, an ultrasonic endodontics device, a "louvered television screen", an ultrasonic meat tenderizer, and an ultrasonic dry cleaning machine.
