Right, but RDS would make a good low cost starting point for an
expanded
FM
text service. And we'd have it, if somebody thought there was real
money
in
it.

Nobody wants to fight for RDS as it has no competitive advantage and is
not
applicable to AM. As I said, it was developed for European simulcasts to
allow automatic signal seeking, which is not an issue in the USA.



So, radio text needs every potential reader to eke out a profit? 60% of
the
audience would not have been enough?

texting alone is not a salable benefit. I can't think of a way to make it
so. It is, however, an added benefit, especially to HD digital audio.
