This episode traces one of broadcasting's strongest genres - from its beginnings in radio through its heyday in the late 60s. Bob Barker talks about his earliest work, and Merv Griffin details his creation of "Wheel of Fortune" and "Jeopardy." Monty Hall recounts his compelling rags-to-riches story and Betty White remembers her role as the first female emcee. Clips for this episode are wide-ranging and include Phyllis Diller's very first TV appearance - as a painfully shy contestant on Groucho Marx's "You Bet Your Life."
