Thomas Aquinas "Tom" Marr (October 17, 1942 – July 7, 2016) was an American talk radio host on WCBM (680-AM) in Baltimore, Maryland, known for his conservative political views. He spent nearly 20 years as a newsman and sportscaster, including eight seasons as a radio play-by-play broadcaster for the Baltimore Orioles. His radio career spanned close to fifty years, mostly in Baltimore, although he worked in other major markets, including Washington, D.C., Philadelphia, and New York City.
While in high school, Marr hosted a high school sports show on WWDC-AM in 1960. After graduating from Montgomery Blair High School of Silver Spring, Maryland, Marr served in the United States Marine Corps until being discharged in 1963. Marr then worked for radio stations in Rhode Island and Salisbury, Maryland then became an announcer for WTAR of Norfolk, Virginia. In 1967, Marr became an anchor and news director for WFBR of Baltimore, and was a panelist and commentator on the award winning call-in show Conference Call. Additionally, he covered the Baltimore Orioles, Baltimore Colts, and the NBA's Baltimore Bullets for CBS Radio. In the mid-1970s, Tom worked for three years as the weekend sports anchor on Baltimore's WMAR TV (Channel 2).
From 1979 to 1986, Marr was a radio play-by-play broadcaster for the Baltimore Orioles on the team's flagship station WFBR. After the 1986 season, the Orioles broadcast rights went to another station, and Tom utilized his roots as a newsman and political commentator to embark in what would ultimately evolve into his talk radio career. In addition to his WFBR talk-show, Marr was hired by Philadelphia's WWDB (FM) to host a similar political talk radio show on weekends.
