Actually, the audio portion of a standard TV signal, IS FM. The video portion is analog and is Amplitude Modulated because the signal needs a wide enough bandwidth to provide a usable signal. So, an FM televison signal is NOT possible...
The video portion of a TV signal is in a Vistigal Sideband mode. The lower, or vistigal part of the sideband signal, is filtered out, this makes it possible for the positive sideband to be expanded enough to give the 4.5 Mhz or so bandwidth necessary for a usable color signal.
The very first TV transmissions were done in the standard AM mode of a carrier with double sidebands.
Of course, with digital TV transmissions techniques, the whole spectrum changes and the concept of AM and FM is meaningless.

that's quite available. in case you have a channel 6 (over the air) on your section, music your fm radio to love 87.7 or 87.9. Channel 6 could be heard on a sort of FM frequencies.

Yes it's possible, will it happen here in Australia? No. Why? Because it's like having an alternative for oil. Fat cats will loose money.
