Matt Rogers, one of the 12 finalists on this year's "American Idol", was a contestant with several other of his family members on "Family Feud" as hosted by Louie Anderson, and there were clips shown. ("Idol" is also produced by Fremantle Media, so I would assume there was no problem getting the clip.)
And we all remember Ryan Seacrest's game show past as the host of "Click" (that Merv Griffin-created Internet quizzer).
