AOL stepped up its transformation from internet access provider into an ad-driven business on Monday as it announced plans to move its corporate headquarters and consolidate its advertising operations. AOL's senior executives, ad sales representatives and content producers will move next northern spring to New York's Greenwich Village, bringing them closer to the heart of the media-advertising industry. AOL is currently based in Dulles, Virginia. "By putting our headquarters there, we're sending a clear signal to the market that AOL intends to lead in this space," Chief Executive Randy Falco told employees on Monday.
