Historic US Bandplan
Early FM broadcasting in North America originally used the 42–50 MHz band (this range was also used by a class of experimental wideband AM stations known as apex broadcasters). Shortly after World War II the United States FCC decided to move FM broadcasters to the 88.1–105.9 MHz band (later extended to 107.9 MHz). Only non-commercial stations can use the 88–92 MHz range.
In March 2008, the FCC requested public comment on turning the bandwidth currently occupied by analog television channels 5 and 6 (76–88 MHz) over to extending the FM broadcast band when the digital television transition was to be completed in February 2009 (ultimately delayed to June 2009). This proposed allocation would effectively assign frequencies corresponding to the existing Japanese FM radio service (which begins at 76 MHz) for use as an extension to the existing North American FM broadcast band.

Famous quotes containing the word historic:
“If there is any period one would desire to be born in, is it not the age of Revolution; when the old and the new stand side by side, and admit of being compared; when the energies of all men are searched by fear and by hope; when the historic glories of the old can be compensated by the rich possibilities of the new era?”
—Ralph Waldo Emerson (1803–1882)
