Then: Credited with making 'Total Request Live' the must-watch afternoon entertainment it became, former radio disc jockey Carson Daly debuted on the series in 1998 and stuck with it until 2002. In that time, he became a celebrity in his own right, thanks in part to his high-profile romances with the likes of Tara Reid and Jennifer Love Hewitt.

Now: The charismatic Daly parlayed his celebrity into his long-running NBC talk show 'Last Call with Carson Daly,' which has now been on the air for over ten years. In 2010, he also became the show's executive producer. And just last year, he earned his first Emmy nomination for hosting the singing competition 'The Voice.'
