'Come on down!' Contestants guess retail values for prizes on TV's longest-running game show. Bob Barker racked up over a dozen hosting Emmys since CBS first aired the daytime staple in 1972, though it originated with Bill Cullen on NBC (1956-63) and ABC (1963-65). However, it was the genial, ageless Barker who really sold viewers on the show, which spawned several syndicated offshoots and a string of prime-time specials. When Barker retired in 2007, Drew Carey stepped in to ably fill his shoes.
