saving of Sirius XM lead to any sort of Sirius-DirecTV tie-up? Earlier this week, Liberty Media (which owns DirecTV) decided to loan the nearly bankrupt Sirius XM $530 million in exchange for a 40 percent equity stake. Now, DirecTV is a direct cousin of yet another satellite-based company. We already knew that both DirecTV and DISH were considering the merits of mobile TV, but according to a new report from Reuters, this could be the deal that finally urges the former to pursue it. Liberty Chief Executive Greg Maffei stated that it "would be looking at the possibilities of co-marketing DirecTV and Sirius XM to each other's subscribers and joint content deals, as well as working on a mobile video initiative." Of course, those weren't the primary reasons the deal was done, but only time will tell if it was lingering on the back of Liberty's mind as the ink dried.
