In LA, there are nearly a dozen HD-2 channels already active, all with
previously uncovered niche formats. Serving listener groups is not QRM.



Are these niche formats expected to get people listening to the radio when
they otherwise would not be listening? If IBOC significantly expands the
audience, I can see an advantage for both the audience and the advertisers.

However, my Inner Conspiracy Theorist keeps telling me that IBOC won't
expand the total radio audience much, if at all, and multicasting's biggest
effect will be in drawing advertising revenue away from from the smaller,
non-IBOC stations.
