• Watch Liberty's John Malone at the D7 Conference

    If you have a spare 10 minutes, have a look at this interview Walt Mossberg did with John Malone yesterday at the D7: All Things Digital conference. Malone, who's now chairman of Liberty Media/Liberty Global, was the head of cable giant TCI for many years. Nobody on planet earth knows more about how the cable TV business works than Malone, and his responses to Mossberg's questions about how premium TV programming will or won't shift to online and a la carte availability are well worth listening to.
