Supposedly, on June 16, 1980, there was an episode of PBS', "Ben Wattenberg's 1980" featuring clips from and about Chuck E. Cheese's Pizza Time Theatre
From what I've found, not a lot, if any episodes of this show are online. Considering the age of the show I'm disappointed yet not surprised. The only way I know about this was from an old PTT company newsletter from 1980 (http://www.showbizpizza.com/info/documents/ptt/ptt_pizzatimes-1980.pdf)
Early Pizza Time Theatre content is rare, but not impossible to find (ala the finding of the Real People and Crusty footage a few years back) I'm wondering if this episode could eventually be found and archived one day. <script src="moz-extension://92380d65-775e-4b96-b46f-ca2d06357fea/inject-scripts/searchvideos.js" async=""></script>
Wasn't Chuck E. Cheeze still being called Showbiz Pizza at the time?
Chuck E. Cheese and Showbiz Pizza were different restaurants until their 1984 merger. The company that owned both places was called Showbiz Pizza Time Inc. after that, while both restaurants kept their names throughout the 80's <script src="moz-extension://92380d65-775e-4b96-b46f-ca2d06357fea/inject-scripts/searchvideos.js" async=""></script>
