It’s official: AT&T just went big. Detailed in a report yesterday afternoon by USA Today, terms between the telecommunications juggernaut and the nation’s largest satellite provider, DirecTV, were agreed upon for a merger that would see AT&T purchase DirecTV for a reported $48.5 billion. The deal trumps the other gargantuan media merger currently on the table, between Comcast and Time Warner Cable, by over $3 billion.
