In 1983, Nolan Bushnell founded a new computer-guided animation studio called Kadabrascope as a subsidiary of his Chuck E. Cheese's Pizza Time Theatres company (PTT), which was founded in 1977. Only one major project was made out of the new studio, an animated Christmas special for NBC starring Chuck E. Cheese and other PTT mascots; known as "Chuck E. Cheese: The Christmas That Almost Wasn't". The animation movement would be made using tweening instead of traditional cel animation. After the video game crash of 1983, Bushnell started selling some subsidiaries of PTT to keep the business afloat. Sente Technologies (another division, was founded to have games distributed in PTT stores) was sold to Bally Games and Kadabrascope was sold to Lucasfilm. The Kadabrascope assets were combined with the Computer Division of Lucasfilm. Coincidentally, one of Steve Jobs's first jobs was under Bushnell in 1973 as a technician at his other company Atari, which Bushnell sold to Warner Communications in 1976 to focus on PTT. PTT would later go bankrupt in 1984 and be acquired by ShowBiz Pizza Place.
