Chuck E. Cheese's Pizza Time Theatre was founded in 1977 with the goal of bringing video games to the mainstream. Pizza Time Theatre was acquired in 1984 and merged with Showbiz Pizza Time, Inc. In 1990, the two brands were combined and renamed Chuck E. Cheese's Pizza, eventually dropping the word, pizza.

The first two sets of Minis are dated 1983 (Pizza Time Theater) and 1991 (Showbiz Pizza Time). They are both Asian molds (some say Hong Kong, others China) 3.5" diameter, hard plastic, flight rings on the outer top edge, and black hot stamp of Chuck E Cheese. Known colors are red, green and yellow (1983) and pink, green, yellow and red (1991).

The Minis with labels are the same size as the 1983 and 1991 versions, but the mold has an additional flight ring. They are made in China. The Chuck E Cheese character is the one used from 1977 to 1994.

The Skimmer Rings are the smallest I've seen at 2.5" diameter. They have "Chuck E Cheese" embossed on top.
