Maybe someone can link a quote on this, but I have seen nothing from the FCC, Congress, or the radio industry that says they'd like to have DAB here. In fact, the FCC has had a stated policy against DAB. The radio industry has nothing to gain by giving up their expensive towers and transmitters. They are grandfathered into lots of huge benefits by retaining the status quo, including the music royalty exemption. DAB would require them to pay billions in royalties to record labels, and makes hundreds of millions of FM radios obsolete. Clearly, the public has already shown an unwillingness to buy new radios, whether they receive HD, satellite, or internet. None of the new sets are selling well. The public is happy with the status quo, and if anything, their device of choice is mobile. The radio companies have already begun transitioning transmission onto platforms that can be received on cell phones. So any legislation in this regard would be counter to the public and the industry.
