I've seen this video and I Think it's really interesting. The Brock story is totally true. In the merger, ShowBiz bought PTT, Inc. PTT Would have died if they didn't. Nolan's company never really survived. The Chuck E. Cheese name you see today is ShowBiz Pizza. The crash of '83 didn't really help either. He also fails to mention that Showbiz didn't actually own the Rock-afire so there was no way to keep them without buying the rights, to which the owner still keeps to this day, but they now owned the Chuck E. characters so they were kinda forced to use them.
In many people's eyes Showbiz was the more teenage and better place, and I Do think they did the right thing..Nolan should be happy about them since they kept his company alive. *shrugs*
