Mark Goodson–Bill Todman Productions (and to a lesser extent, Barry-Enright Productions, Chuck Barris Productions, Jay Wolpert Productions, and the post-1980 Merv Griffin productions) and to an even lesser extent Heatter-Quigley Productions had the foresight to preserve many of their games for later reruns; for years, these shows dominated the USA Network's game show block, then the Game Show Network (GSN) line-up and now make up a major portion of Buzzr TV's lineup. "You Bet Your Life" was saved from destruction only because host Groucho Marx allowed NBC to give him the recordings they were otherwise going to throw out.
