The confirmation was unanimous, TVWeek.com reported.
Martin, who has been on the FCC since July, 2001, became the agency's chairman in March 2005.
The commission is currently facing challenges as it reviews media ownership rules. Also, the FCC is expecting increased criticism from the newly elected Democratic Congress on transitioning to digital TV and on broadcasters' obligations to public interest.
Prior to joining the FCC, Martin was a special assistant to President George W. Bush for economic policy, TVWeek.com reported.
"I look forward to working with the Administration and Congress," Martin said in a statement. "As well as with my fellow commissioners and the incredibly able staff at the FCC to ensure that all Americans share in the benefits and opportunities offered by the best communications system in the world."
