If the idea of Comcast buying out Time Warner Cable to become the largest cable company in America wasnt enough to make you worry about media consolidation, news tonight from the Wall Street Journal just might. Reportedly, ATT has approached DirecTV to begin possible acquisition talks, a deal that the WSJ says could be worth over $40 billion. If it were to happen, it would give the combined company something on the order of 26 million TV subscribers, making it second only to the hypothetical Comcast/TWC combination of 30 million. DirecTV could be looking to make a deal.
