In early 1993, Jacor Communications, now Clear Channel, would eventually answer this demand. In 1991, WRBZ changed its call letters to WAQZ. The station was called 'The Heat' and carried a satellite-fed top 40 format (there were no local jocks on air). Jacor Communications, who at the time also owned the market's long time album-oriented rock station WEBN, wanted to compete with new rival Z-Rock, at 96.5, a satellite-fed hard rock station based out of Dallas, TX. Jacor purchased the station in late 1991 and flipped formats to a locally programmed hard rock format. The name was changed to the 'Power Pig'. There were no on-air personalities, only voice overs and jocks from WEBN would do rock reports which would air occasionally. The voice-overs which aired often took aim at Z-Rock and jocks from other local stations, one being Mark Sebastion, who at the time was at Top 40 station Q102. Jacor would eventually succeed in its mission to wipe out competitor Z-Rock, as they went off the air in September 1992, switching to a country format, leaving the Power Pig the only hard rock station, other than sister WEBN. In the spring of 1993, in the wake of a changing music scene and the decline in popularity to the station's hair-metal rock format, Jacor flipped the format and the 'Power Pig' name and switched to a new alternative format called Channel Z.
