While AT&T Does Deals, Verizon Spends to Hone Its Networks - New York Times: "To offer that service, Mr. Whitacre is taking a less costly -- but also less proven -- approach to his fiber network rollout than Mr. Seidenberg. AT&T is stringing fiber lines to neighborhoods and using the existing copper lines to connect the rest of the way to homes. It is expected to spend about $12 billion on its network by 2010 to serve nearly 32 million homes (including those of BellSouth customers), according to Bernstein Research.
Verizon will spend about $18 billion by 2010 to run fiber lines into people's homes, Bernstein says. The Verizon network will serve half that number of customers, but will offer more bandwidth than networks run by AT&T and the cable companies. "
