Radio broadcasting uses either of two types of signals -- AM or FM.

FM broadcasting is a broadcast technology invented by Edwin Howard Armstrong that uses frequency modulation (FM) to provide high-fidelity sound over broadcast radio.

FM signals do not need expensive transmission towers.

FM Radio enables a great degree of localization and hence brings along interactivity with a local flavour, at relatively low broadcast costs, which cannot be matched by television.
