The announcement is part of an overall broadband initiative introduced Thursday at the Consumer Electronics Show in Las Vegas by Verizon CEO Ivan Seidenberg. On a conference call with the press, Seidenberg said Verizon is committed to investing a total of $3 billion in its networks over the next two years to bring broadband to the mass market. That figure includes the increase in the wireless-service budget, along with $2 billion earmarked for enhancements to the company’s wireline network. While the money devoted to landline projects could turn out to be a reallocation of funds, a company representative confirmed that the $1 billion promised for the wireless build-out will be in addition to funds already budgeted. In both 2002 and 2003, Verizon spent about $4 billion on wireless.
