Federal Communications Commission Chairman Julius Genachowski will be leaving his post in the coming weeks, he announced today. He was nominated to lead the agency in 2009 by President Obama.

Earlier this month, Genachowski threw his weight behind the administration's desire to repeal the ban imposed by the Copyright Office of the Library of Congress on unlocking cellphones. "From a communications policy perspective, this raises serious competition and innovation concerns, and for wireless consumers, it doesn't pass the common sense test," he said in a statement. "The FCC is examining this issue ... I also encourage Congress to take a close look and consider a legislative solution."

In remarks to FCC staff this morning listing the agency's accomplishments over his term, he said:

"Over the past four years, we've focused the FCC on broadband, wired and wireless, working to drive economic growth and improve the lives of all Americans ... Today, America's broadband economy is thriving, with record-setting private investment; unparalleled innovation in networks, devices and apps; and renewed U.S. leadership around the world."
