The 1969 television show that was canceled halfway through it's 1st ever episode actually had two episodes. It was sponsored by Bristol-Myers which today is Bristol Myers Squibb. You can only find the full episodes at the Paley Center for Media which is temporarily closed but when they open I would be curious to see the footage to understand the hype and reasons it got canceled after only 1 episode. The other show this happened to was in Australia called Australia's Naughtiest Home Videos.
