For fifteen years CNN’s Larry King Live was a staple of nighttime cable television. It was the most watched program on the network and its host held court to musicians, movie starts, heads of state and newsmakers of the day. Maybe that’s what prompted Lady Gaga to ask him whether or not his name was really "King Larry?" But last night, Larry King wrapped his final episode in an interview with a star-studded show where even current and former presidents found time to make an appearance. Will he be missed, and can he be replaced?

Dr. Laura Schlessinger is ending he radio talk show, "The Dr. Laura Program" after 30 years on the air. She came under fire earlier this month for using the N-word eleven times in five minutes during an on-air conversation about racism. On "Larry King Live" last night, Dr. Laura defended her decision, saying, "I want to be able to say what's in my mind and in my heart and what I think is helpful and useful without someone getting angry, without some special interest group deciding this is a time to silence a voice of dissent."

The Saturday night resignation of White House green jobs advisor Van Jones is as much a story of politics as it is about cable television, as well as the drive and magnetism of Fox News talk show host Glenn Beck. Beck's show on Fox News draws around 3 million viewers a night, and it was his targeting of Van Jones that lead to Jones’ resignation.

While President Obama seems to be struggling to get his message across, Glenn Beck has no problem being heard loud and clear. To understand Glenn Beck's popularity, we speak to Michael Harrison, the publisher of Talkers Magazine, the leading trade publication for the talking-head set, along with Robert Thompson, professor of Television, Radio and Film at Syracuse University.
