The text ability could be a new revenue stream. Might end up being used
for commercials.


Just to be complete, IBOC isn't necessary to send radio text. FMers have
been able to send text in a limited form with RDS. It's kinda nifty, but
RDS text hasn't set the world on fire.

It is necessary to send on AM, though. And RDS was created to do something
which is almost unknown in the US... skip from transmitter to transmitter of
national simulcast networks.
