Insomnia took me to Amazon to look for their old offerings, and I found something interesting with a few more game show gems - "Watch Around The Clock". Each "episode" is 6 hours, and there are 4 of them, for 24 hours to "watch around the clock". It looks like this was a DVD offering as well, but Amazon's got both the B&W and color. Episode 2 is "Daytime Variety", with the description saying "Say the secret word... FUN! Play along with classic trivia, stunts and challenges from iconic TV game shows including The Price is Right, What's My Line and Twenty-One". They look to be peppered with old commercials as well.
Unfortunately, the color "Daytime Favorites" includes no game shows.
