 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.
