second radio station in the market among the 18-34 audience, only losing to WRMF. ARS dissolved its joint sales agreement to operate WPBZ on October 31, 1996, citing a "changing regulatory climate". WPBZ was cited in 1998 as "a highly successful model" for the alternative format. Palm Beach Radio sold its cluster, along with a station in Buffalo, New York, to Infinity Broadcasting, later known as CBS Radio, in 2000 for $4 million and assumption of liabilities. The move made WPBZ the sister station to WEAT and WIRK. WPBZ aired The Howard Stern Show from 2004 to 2005, when he was replaced by David Lee Roth amid Stern's move to satellite radio. Now 103.1 and the move of WIRK to 103.1 On December 5, 2011, WPBZ changed its format to adult top 40, branded as Now 103.1. The Buzz active rock format moved to the HD2 subchannel, replacing the alternative-formatted Buzz Lite. It was the second hot AC station under CBS Radio using the Now FM branding, the first being on Sacramento, California's KZZO.

Later in 2013, Palm Beach Broadcasting and its sister company GoodRadio.TV was merged into Goodman's larger holding company Digity, LLC. Digity was in turn acquired by Alpha Media in February 2016. On September 27, 2018, Alpha Media announced the sale of its West Palm Beach stations to Hubbard Broadcasting. The sale was consummated on January 23, 2019 at a purchase price of $88 million.
