The station signed on the air on December 6, 1961. It was founded by broadcaster Ross Mulholland, who had worked at WJR and several other area stations. The original construction permit for the station bore the call sign WQTI, similar to Mulholland's easy listening-formatted AM station, WQTE (560 AM, now WRDT), but the station was never on the air with those call letters. Upon signing on, the call letters were WGPR.

Saturdays were “Old School Saturdays”, featuring a wide variety of classic R&B, soul and dance-oriented oldies. Genres played on OSS included disco, funk, 1980s electronic music, dance music, Motown, urban oldies, and 1970s R&B. Sundays were devoted mostly to urban gospel programming. According to the September 2011 PPM Ratings release, WGPR ranked #20 (2.1) in the Detroit market.
On October 21, 2011, Radio One announced that it would take over WGPR under a local marketing agreement (LMA), and move WHTD’s urban contemporary format to the station as Hot 107.5. Meanwhile, WHTD was to flip to an urban gospel format as Praise 102.7 on October 31. On October 24, WGPR signed off as Radio One assumed control, and began stunting with a loop of “It’s So Hard to Say Goodbye to Yesterday” by Boyz II Men. This was interspersed with promos redirecting WGPR listeners to Radio One’s urban AC station WDMK (whose competition was neutralized by the format shuffle).[4]
On June 10, 2019, Urban One announced that it would not renew its LMA with WGPR when it expired at the end of 2019. The same day, Beasley Broadcast Group announced that it would acquire WDMK and its Detroit Praise Network stations for $13.5 million
