"They do own 1-800-Free411, but that is not the reason we acquired them; in fact, this is a declining minority of their total call volume," Pete Christothoulou, COO of Marchex,
stated. "The core rationale for the acquisition was ... mobile voice search is an important product for our call advertising network."
Marchex has evolved its business over time to focus on calls and has built a call-based ad network that spans traditional media, online and mobile. The company services national clients and small businesses through partners that include Canada's Yellow Media/Yellow Pages Group, AT&T Interactive and Skype.
