AP: Liberty Media's John Malone warns Comcast-NBC marriage could lead to more mega mergers

Liberty Media Chairman John Malone says Comcast's plan to buy NBC Universalcould prompt competitors to explore their own tie-ups.

In an interview with the Associated Press, Malone said a combined Comcast and NBC Universal would have too much market power and would force competitors to "look pretty hard on how they can protect themselves from the kind of market power that that would represent."

Malone is chairman of Liberty Media Corp., which controls satellite TV provider DirecTV Group Inc. NBC Universal includes broadcast and cable channels, film studios and theme parks.
