Satellite radio gets weirder: Bob Dylan turns DJ

XM Satellite Radio has signed Bob Dylan to do a weekly hour-long broadcast beginning in March. The network offered Dylan a completely open format, commercial-free. So far, Bob plans to fill the time talking, playing music and interviewing guests, although most intriguing is the announcement that he'll also answer email he gets on the air. What's not announced is how much he's being paid, but it couldn't come close to the $500 million Howard Stern is getting from rival Sirius Satellite Radio. How either network affords anything would be the most interesting announcement of all, since neither has made a profit since they started: 1999 for Sirius, 1994 for XM.
