Study: Few consumers know that HD Radio offers multicast capability

A radio audience research firm found that only one percent of respondents to a telephone survey knew that HD Radio can provide more channels of programming. "Our research reveals that radio needs to explain HD Radio and its benefits for listeners," writes Mark Kassof. Meanwhile, Rob Pegoraro of the Washington Post writes that he returned his Boston Acoustics HD Radio out of frustration with the on-again, off-again status of a few multicast channels in the Washington area.
