Most histories of WHTZ (Z100) New York start with the city’s one-time top 40 powerhouse WABC flipping to the news/talk format in May 1982. While that change was emblematic, top 40 had been dormant for a while in New York. WABC really had been an AC station for a year or so, struggling to compete with WNBC, which was a top 40 chart reporter but in actuality was an adult top 40 station. On FM, where top 40 had never really gotten a foothold, WXLO (99X) had gone adult top 40, then R&B/hip-hop. WPIX tried to fill the void for less than a year.
