Government, police, fire and commercial voice services also use narrowband FM on special frequencies.

For instance, in the game that I'm writing I am using six-channel FM synthesized sound.

Normal (analog) TV sound is also broadcast using FM.

Thailand has an 80 channel CB-style service using FM between 245.000 and 245.9875 MHz.

A satellite transmission system uses uncompressed FM.

They generally broadcast in a preallocated very high frequency (VHF) range using FM.

The BBC's main station Radio 1 left medium wave only in 1994, but had been using FM full-time for six years previously, part-time before 1988.

In 1987 40 additional frequencies were added, which were ironically the same as the U.S. allocation - but again using FM.

This has left the AM band almost dry, since most local broadcasters are using FM.

In early 70's some pirate radio started to broadcast using FM.
