[edit] History

The station, which was owned by Horvath Broadcasting until being sold in 2005 to Catholic group owner Starboard Broadcasting.

WZUM began in the 1960s as an R&B and top 40 station, owned by popular Pittsburgh polka bandleader Jimmy Pol. During the 1970s, WZUM was a freeform AOR outlet from noon until dusk, (broadcasting polkas in the morning), until it switched to religious programming under the WPLW callsign in 1975 after its purchase by Robert Hickling. In 1998, following Hickling's death, it was sold to Pittsburgh area broadcaster Mike Horvath and returned to WZUM, changing to smooth jazz, but went dark after just one year with the format. The station later returned after a major transmitter and studio overhaul with time-brokered programming, then oldies, with Catholic programming added in 2002. Upon purchase of the station, Starboard converted it to 100% Catholic programming.

Recently, WZUM applied for an upgrade to its signal, which will give the station minimal night power.
