A paragraph in the FCC’s annual performance report for fiscal year 2012 suggests the agency is on the warpath against unlicensed broadcasters:
The FCC shut down hundreds of pirate broadcast operations, which threaten the integrity of the nation’s communications infrastructure and caused interference to licensed broadcasters, air traffic control frequencies, and other public safety communications. There were $289,000 in penalties and 583 warnings issued during FY 2012.
Specious claims of the pirate threat aside, these numbers were quickly parroted by the Clear Channel-owned trade publication Inside Radio as evidence of a "pirate crackdown confirmed." But there’s no data to back up these claims.
