Computer Aided Tracking System (abbreviated as C.A.T.S. or CATS) is a first digital ball-tracking system used in bowling centres. C.A.T.S. was introduced way back in 1980 by USBC (United States Bowling Congress), United States Bowling Congress. It helps to provide information which the human eye cannot catch quickly or human brains cannot understand immediately. This device can be used by spectators, bowlers, coaches and is even useful for writers. The technology was invented by American Bowling Congress and Women's International Bowling Congress in Greendale, Wisconsin.
