Cedar Hill tower collapse on October 12, 1996. Three workers were killed and one injured when a gust of wind caught the gin pole being used for construction of a new antenna for KXTX-TV. With their tower on the ground, the stations scrambled to get back on air. They were forced to use an auxiliary site for many months, though at a much reduced power output. Because of this, KRBV's ratings sank, and the station was unable to return to its success prior to the tower collapse. Also in 1996, the Infinity Broadcasting Corporation (part of CBS Radio) bought Granum Communications, acquiring KRBV and KOAI. In December 1998, KRBV re-added hip hop music to its playlist, and was revamped as Adult Mix V100.3. 1999-2004: Top 40 On March 12, 1999, the station began stunting by looping songs from artists such as Rob Base and Eminem. Three days later, on March 15, the station changed formats to Rhythmic-leaning Top 40. The station was renamed Hot 100, calling itself DFW's Party Station. On May 28, 2001, at 11 a.m., the station changed its name again to Wild 100 while maintaining its Rhythmic-leaning Top 40 format. The first song on Wild was "Wild Thing" by Tone Loc. Wild became the Dallas affiliate for the Austin-based "J. B. and Sandy" morning show. On March 8, 2002, the station exhumed an old KLIF stunt by declaring themselves a "thing of the past." The station went dark for about three hours and came back with the same format and name. Later that year, J. B. and Sandy's show was terminated. The station became a CBS Radio station when Infinity was renamed in December 2005. On the morning of April 1, 2004, as an April Fools' Day joke, the station's morning show was replaced by a pre-recorded episode of The Russ Martin Show. Later that day, Russ Martin was back on his regular station, Live 105.3, where he got calls from Russ Martin show listeners who thought this change was permanent. Little did anyone know a major change was on the horizon for 100.3 FM. 2004-present: Jack FM On July 1, 2004, at 8 a.m., the station began stunting with a mix of music and soundbites featuring the word "Jack." At Noon (following a skit in which station voiceover Sean Caldwell became increasingly tired of constantly hyping the station, and happened to receive a visit from his
