The FM broadcast band, used for FM broadcast radio by radio stations, differs between different parts of the world. In Europe and Africa (ITU region 1), it spans from 87.5 to 108.0 megahertz (MHz), while in America (ITU region 2) it goes only from 87.7 to 108.0 MHz. The FM broadcast band in Japan uses 76.0 to 90 MHz. The OIRT band in Eastern Europe is from 65.8 to 74.0 MHz, although these countries now primarily use the 87.5 to 108 MHz band, as in the case of Russia. Some other countries have already discontinued the OIRT band and have changed to the 87.5 to 108 MHz band.
Frequency modulation radio originated in the United States of America during the 1930s; the system was developed by the American electrical engineer Edwin H. Armstrong. However, FM broadcasting did not become widespread even in North America until the 1960s.
Frequency-modulated radio waves can be generated at any frequency. All the bands mentioned in this article are in the Very High Frequency (VHF) band, which extends from 30 to 300 MHz.
In some languages, the VHF band is referred to as "UKW" (from the German Ultrakurzwelle — "ultra short wave") or "УКВ" (from the Russian Ультракороткие волны).

Famous quotes containing the words broadcast and/or band:
“Listening to a news broadcast is like smoking a cigarette and crushing the butt in the ashtray.”
—Milan Kundera (b. 1929)
“What passes for identity in America is a series of myths about one’s heroic ancestors. It’s astounding to me, for example, that so many people really seem to believe that the country was founded by a band of heroes who wanted to be free. That happens not to be true. What happened was that some people left Europe because they couldn’t stay there any longer and had to go someplace else to make it. They were hungry, they were poor, they were convicts.”
—James Baldwin (1924–1987)
