CHANGING CHANNELS: The chairman of Federal Communications Commission, Julius Genachowski, said Friday that he's resigning in the next few weeks. The Obama appointee has held the post since 2009.

CALL RECORD: Genachowski's FCC helped block one mega-merger, between AT&T and T-Mobile USA, and let through another, that of Comcast and NBC. It's worked to further broadband adoption and get more wireless spectrum into the hands of phone companies who can use it.

STAY TUNED: Analysts believe Tom Wheeler, and a former venture capitalist and head of two telecom trade groups, could be next in line.
