"[6] In a landmark case, Cox v. Susquehanna Broadcasting, the judge was handed a digital radio and asked to tune to 100.0 MHz.

Z-93 eventually lost its lead, and shifted to a more rhythmic contemporary format as "Hot New Z-93" before flipping to classic rock in January 1989.

[12][13] However, declining ratings, as well as the success of Nirvana at the end of 1991 and the subsequent rise of "alternative" music, gave station management pause.

[14] In early September 1992, Susquehanna brought in Will Pendarvis to host an all-alternative program on weeknights called "Power 99 On the Edge".

99X became one of the most influential alternative rock stations in the United States, and played a key role in breaking numerous acts during its early years.

Music director Sean Demery's push behind The Cranberries' "Linger" in 1993 helped earn the band national attention in the U.S. On a trip to Australia in early 1995, program director Brian Phillips brought back a copy of fledgling band Silverchair's debut EP, which the station began to spin.

The day after the release of the group's debut album Frogstomp, the band gave its first US performance at the Roxy in Atlanta as a "99X Freeloader Show."

Over the next 20 months, Cumulus continued to support WNNX's alternative rock format, despite a noticeable decline in the Arbitron ratings.

[30][31] This simulcast would be moved to W258BU (99.1 FM) on June 9, 2011; following a few days of airing on both translators, as well as a period of stunting, W250BC would flip to a 80s/90s hits format branded as "Journey 97.9", this time relaying WWWQ's HD3 subchannel.

[45] WWWQ-HD2 would temporarily lose its translator simulcast on April 12, 2018, when W255CJ was ordered off-air by the FCC due to interference complaints by WWGA in Tallapoosa.
