"The radio conglomerates, chipmakers and other companies behind HD radio--a digital form of broadcasting that essentially fits into the same spectrum as current analog channel--say their campaign to promote the technology is about to begin. The push on HD radio is a combination of opportunity and desperation, Walsh and others concede. In HD radio, up to eight separate stations can be squeezed into the same spectrum currently allotted for a single station. As a result, broadcasters can offer multiple channels of related programming; a classical station, for instance, could dedicate channels to chamber music or opera. Ideally, this will lead to more listeners and advertisers."Is this the right step for traditional broadcasters to attempt to counter the threat (or at least a perceived threat) from satellite radio? I think maybe, but it depends on their implementation. If they use the extra channels to just pump out more of the same, then their is not much benefit, but if they use it to narrow cast to a more specific audience, they might just be on to something. What do you think?
