Probably topping the list was the release of long-anticipated “final rules” for IBOC, with the FCC’s Second Report and Order on DAB, adopted in March (although not effective until Sept. 15).
Among other things, this made it possible for broadcasters to begin FM IBOC multicasting and Extended Hybrid operation without permission or notice. It also allowed AM IBOC broadcasting at night — a topic that has subsequently proven quite controversial, resulting in numerous complaints, the formation of an anti-IBOC coalition, and one radio group’s (Citadel’s) at least temporary cessation of AM IBOC operation. This debate will undoubtedly continue in 2008.
There were other, more positive IBOC-related movements in the industry during 2007, which you may recall from their in-depth coverage on these pages, and which will likely reappear in more real form in 2008.
