==Program formats==
{{Main|Radio format}}

Radio program formats differ by country, regulation, and markets. For instance, the U.S. [[Federal Communications Commission]] designates the 88&ndash;92 megahertz band in the U.S. for non-profit or educational programming, with advertising prohibited.

In addition, formats change in popularity as time passes and technology improves. Early radio equipment only allowed program material to be broadcast in real time, known as ''live'' broadcasting. As technology for [[sound recording]] improved, an increasing proportion of broadcast programming used pre-recorded material. A current trend is the [[automation]] of radio stations. Some stations now operate without direct human intervention by using entirely pre-recorded material sequenced by [[computer]] control.
