Development of the system began in 1976, and it was demonstrated and sold as the first personal computer for the masses at the January 1977 Consumer Electronics Show. The name "PET" was suggested by Andre Souson after he saw the Pet Rock in Los Gatos, and stated they were going to make the "pet computer". It was backronymed to Personal Electronic Transactor. Byte referred to the PET, Apple II and Tandy TRS-80 collectively as the "1977 trinity".
Following the initial PET 2001, the design was updated through a series of models with more memory, better keyboard, larger screen, and other modifications. The systems were a top seller in the Canadian and United States education markets, as well as for business use in Europe.
The PET line was discontinued in 1982 after approximately 219,000 machines were sold.
