WPSV (AM)

WPSV (AM) (740 AM) is a commercial radio station in Chicago, Illinois. The station is owned by Urban One and carries an urban gospel format. WPSV's studios are located at the 16th floor of 303 East Wacker Drive in the Chicago Loop, with transmitters being located atop the Willis Tower in the Loop.

WPSV (AM)'s programming is also simulcasted on WPSV-FM.

Classical music
On March 5, 1946, WAPM would mark its debut. The station was first owned by the Chicago Educational Learning Company, and it carried a classical music format. WAPM was among one of the first classic music stations, and was also the most popular one during its run. On July 7, 1954, a sister FM station would launch as WAPM-FM (now WJKA-FM).

For 42 years, the station and its sister FM station were owned by the local Chicago Educational Learning Company, but in 1988, both WAPM and WAPM-FM were sold to the then small Nassau Broadcasting Partners. Nassau would then grow as a company by purchasing more classical music stations, most notably WCRB in Boston.

Nassau, however, would sell its Chicago radio assets to EZ Communications (owner of WNTY-FM) in 1994. EZ would then merge with American Radio Systems in 1997.

In 1998, ARS would merge with Infinity Radio. However during the merger, Infinity was over the limits and thus sold ARS' Chicago cluster including WNTY-FM, WYCU, WAPM, WCMX-FM, WPTX to the African-American controlled Radio One (later known as Urban One).

Urban gospel
On October 18, 2004, WAPM would drop its longtime classical format and switched to an urban gospel format branded "Praise 740". The station would subsequently change its call-letters to WPSV.

On July 18, 2017, WROI would flip to a simulcast of WPSV, and as a result WPSV would change its branding to "Praise 740-91.7".
