What does it take to be a good TV host? If you're Ryan Seacrest -- who's hosted "American Idol" and "Dick Clark's New Year's Rockin' Eve," among other programs -- it's about putting people at ease and keeping things moving. It's not as easy as it looks. Here are others who have been great at a sometimes underrated job.
Dick Clark, seen here in 1957, was the model of a good TV host. He readily gave up the stage and dance floor to "American Bandstand" visitors, oversaw "The $10,000 Pyramid" and its relations, and appeared on countless music and entertainment specials before he died in 2012. Seacrest co-hosted "Dick Clark's New Year's Rockin' Eve" with him and considered him a mentor.
