Television expert Bob Thompson spoke with Boston Public Radio on Monday about the return of late night television, Tyra Banks' new position as host on Dancing with the Stars, and more. "Tom Bergeron and Erin Andrews, who have been co-hosting Dancing with the Stars, were kind of unceremoniously let go," he said, "but it's not part of any scandal. I think maybe that show just decided to make a switch."

Bob Thompson is a founding director of the Bleier Center for Television and Popular Culture and a trustee professor of television and popular culture at Newhouse School of Public Communications at Syracuse University.
