25 million: Number of SiriusXM subscribers, 12 percent of whom regularly listen to two dedicated Stern channels

Why he matters: In 2005, Stern left terrestrial broadcasting for satellite after landing a five-year deal worth a reported $500 million (he re-upped in 2010 for an additional $400 million; the contract expires in 2015) and by 2013 he proved that he had perfected his interviewing skills with such A-listers as Paul McCartney and Lady Gaga. "I think I've evolved -- God, I hope I have," he says. "My biggest criticism of broadcasters is that they just stick with their ways." Stern certainly has not judging by his extracurriculars, from America's Got Talent on NBC to hosting elaborate pay-per-view events, like his recent 60th birthday party at New York's Hammerstein Ballroom.

Proudest accomplishment this year: Landing coveted interviews with Quentin Tarantino and Lena Dunham, who called in to the show after Stern called her fat on air. Stern says the understanding is that he'll "celebrate [a celebrity's] career and really get into their process of how everything works. Slowly but surely the industry is waking up to it."

Goal for next year: "I'm convinced I could interview Robert De Niro and get him to talk. No one's a bad interviewee."

Secret weapon: "You've got to care," insists Stern. "It would be very easy not to, [but] I never got into radio for the money. It was because I really cared about the medium; I thought I could be my funniest and my best on the radio, not anywhere else."
