As we have only a relatively small number of stations in each state, manufacturers used to print the stations call signs on the dial as it was easier for listeners to find their favorite station.

Packard Bell (was an old radio manufacturer, not the PC marketer) used to do that on their radios. As they were a West coast company, the stations were the ones in California, Oregon and Washington. Stations must have rarely changed callsigns back then; today you couldn't print callsigns on radio dials as every other week someone changes theirs.

Multiband radios included one or more shortwave bands for listening to international broadcasts. As VHF FM broadcasts did not occur until the 1970's, all our tube radios did not have this band.
... instead Digital radio will be a third service that will take over the frequency bands of our soon to be shutdown analog TV service.

IBOC (in band on channel) digital radio seems to cause no real problems for FM, but it impacts AM more severely. Some AM stations use their FM brothers' HD secondary channels to broadcast in digital the AM programming.
I have had Sirius satellite radio in rental cars, and the compression artifacts sound awful (like overly compressed mp3's). XM sounds better, but has no Howard Stern...
Haven't heard IBOC HD radio.
Broadband and cell phone providers are eyeing our TV bands, wanting to get rid of over-the-air TV broadcast. Claiming that most everyone has cable or satellite TV. My mom doesn't...
