Bally Technologies, Inc. is a manufacturer of slot machines and other gaming technology based in Las Vegas, Nevada. It is the descendant and continuation of the original Bally Manufacturing Corporation of Chicago.
Bally Technologies was founded in 1968 as “Advanced Patent Technologies”.

In 2006, the entire Alliance Gaming Corporation organization was officially renamed Bally Technologies Inc.
