Founded by Allegheny Mountain Network President Cary H. Simpson, WGMR first signed on the air on August 15, 1961, as the FM sister station to WTRN Tyrone.
Though also licensed to Tyrone, WGMR has primarily served State College and Centre County.
Through the years, WGMR has changed formats a couple times, from country to alternative and Top 40 at the turn of the 21st century.
This station was previously owned by the Allegheny Mountain Network, and was sold to Forever Broadcasting of Altoona on July 2, 2008.
On the last day before the sale was final the station turned back the clock for a couple of hours and played Alternative music under the Revolution branding.
