In January 1948, WMAR-FM signed on for the first time at 97.9,[3] owned by the A.S. Abell Company, publishers of the Baltimore Sun and founders of WMAR-TV, Baltimore's first television station. The first station to use that call sign (and not related to the second WMAR-FM at 106.5, now WWMX), WMAR-FM was a collaborative partner of Transit Rides Inc., developer of a music format designed for public transportation and owned by the Cincinnati-based Taft family.[4] After two years on the air, Abell shut down the station in June 1950 and turned in its license to the Federal Communications Commission.[5]

The 97.9 frequency remained silent until December 1958 when WFDS-FM signed on for the first time,[6] a classical music outlet under the ownership of William S. Cook, a Baltimore native and professional engineer.[7] Cook created WFDS-FM as one of the first radio stations in the United States to experiment with stereo.[8] The Hearst Corporation purchased the station in April 1960 and retained classical music while changing the call sign to WBAL-FM.[9][10]

In June 1975 WBAL-FM joined NBC Radio Network's 24-hour national "News and Information Service" (NIS), and was the largest affiliate of NIS not to be an NBC Radio owned-and-operated station.[11] After two years of all-news and low ratings, NBC closed down NIS in late May 1977. But WBAL-FM bailed on the service early, adopting its present elements—the call letters WIYY,[12] rock music format and the 98 Rock branding—on March 28, 1977.


In 2007, the station was nominated for the Radio & Records magazine Active Rock station of the year in a top 25 market award . Other nominees included WAAF in Boston, KBPI in Denver, WRIF in Detroit, WMMR in Philadelphia, and KISW in Seattle.[13] WIYY was a nominee for the 2012 "Major Market Radio Station of the Year" RadioContraband Rock Radio Award.
