Federal Communications Commission Chairman Julius Genachowski says the agency will not release its Allotment Optimization Model (AOM) detailing how it will reconfigure broadcast spectrum after an incentive auction until after it gets that auction authority from Congress, reports Broadcasting & Cable. The statement came in response to a request from Rep. John Dingell (D-Mich.) that reflects the growing call in the broadcast industry to release the model to the public. Dingell called Genachowski’s response “deeply troubling.” He also said he would oppose any legislation that did not explicitly protect broadcasters.
