Z-Rock was a nationally syndicated radio network based out of Dallas, Texas, USA, in the mid-1980s through the mid-1990s that played heavy metal and hard rock music. The format was one of ABC Radio Network’s (now Cumulus Media Networks’) 24-hour satellite formats (formerly Satellite Music Network). Z-Rock debuted on Labor Day 1986 and is credited with being the first nationally focused radio station/network. In March 1990, Z Rock was nominated for Billboard Awards, the only full-time hard rock/metal programming ever nominated in the history of Billboard magazine.[citation needed] After several changes in personnel and programming direction, the network was discontinued on December 31, 1996. During its early days the station drew attention for playing unedited, explicit versions of songs. The station also gained notoriety in the DFW area for their “mascot” vehicle, “the Z Rock hearse”, which was displayed at various events and locations around the DFW Metroplex. The vehicle ultimately was awarded to a lucky winner in a promotional givaway. Dennis C. Weaver of Dallas drew the “lucky key” in a drawing held at Sound Climax, a Dallas car audio store which had outfitted the vehicle with stereo gear to showcase their products.
