The big boys pushed IBOC because they wanted to do whatever they could

and frightening idea to them.

That's part of it, but they also did not want to have to pay for the
additional spectrum on a new band.

- For all the misinformation that our favorite troll promulgates here,

That is because FM Radio has a well defined and
'limited' Broadcast Service Area unlike AM Radio;
which can go far farther then authorized on a nightly
basis each and every night.

Plus FM Radio has NO large legacy culture of DXers
and DXing like the AM/MW Radio Band has/had for
many decades.
