Satellite Radio - On November 18, 2004 the former COO and President of Viacom, Mel Karmazin, was named the CEO of Sirius Satellite Radio Company. Stern worked under Karmazin at Infinity Radio and the two appeared to always have a great deal of mutual respect. It was Karmazin who fiercely protected Stern in the wake of the Super Bowl XXXVIII Halftime Show (produced by MTV and aired by CBS, both co-owned with Infinity-now CBS Radio-until CBS Corporation split off in 2006) and the FCC crackdown on shock jocks and obscenity, in general.
