"In addition, local stations, having already developed expensive
secondary programming for their HD stations that nobody listens to,
are excited to have another outlet for that programming. They see this
as a great salvation from the HD experience, because they’ve already
invested that money, and everything that they’re putting on their
secondary [HD] channels, that their audience isn’t able to hear either
because of the antenna problems with HD, their location, or because
they don’t want to invest in HD radio,” said Sopato. All of those
secondary streams are on the web and on this radio. Now, they don’t
have to tell their audience, ‘go get an HD Radio.’”
