WMBS (590 AM) is a full service/adult standards formatted broadcast radio station licensed to Uniontown, Pennsylvania, serving the Uniontown/Pittsburgh/Morgantown area.

Brian Mroziak is the current general manager, who ascended to that position at the age of 24,[2] making him one of radio's youngest top executives in the country.

That station had been silent for almost two years due to financial problems that eventually forced it and its AM sister WCVI (now WBGI) into bankruptcy proceedings.

As part of a long-term plan for WMBS' future in the late 1990s, the station moved from its longtime rented location on Fayette Street (the original location in 1937 was in the Fayette Bank Building in downtown Uniontown), to a large Victorian house on South Mount Vernon Avenue owned by Pritts' cousin, the late federal judge Edward Dumbauld, thus eliminating the station's monthly rental bill.

Jack McMullen, one of WMBS' pioneers, who completed an 18-year stint with the station beginning in 1945, died in a hit-and-run vehicle-pedestrian accident on West Main Street in Uniontown.

WMBS is the only station in the Pittsburgh Radio Market to carry the CBS World News roundup which celebrated its 70th anniversary on the air in 2008.

WMBS was awarded in 2010 The Most Outstanding Local Radio Newscast from a small market station by the Pennsylvania Association of Broadcasters.
