One of WMAR's early local personalities was Jim McKay, who was the first voice heard when the station began its test broadcasts, and called the horse race program that inaugurated the station's official launch. McKay later moved over to CBS briefly before achieving greater fame on ABC as host of "Wide World of Sports" and Olympic coverage. Another was Helen Delich Bentley, a maritime editor for the "Baltimore Sun" who hosted "The Port That Built a City", a weekly review presenting maritime, shipping and transportation-related news. (Bentley later ran several times and was finally elected as the U.S. Representative from Maryland, serving several terms. By the 2010s, the Port of Baltimore was renamed symbolically for her.)
