In February 1996, WYNY in New York City flipped to the format under the name "103-5 The New KTU", utilizing a "Rhythmic Hot AC" approach with dance-pop tracks added to the mix.
While WDRQ was a moderate ratings success (the station's true ratings boom came after it evolved into a rhythmic-oriented Contemporary Hit format by 1999), KBKS and KIBB were less successful, resulting in KBKS flipping to Top 40/CHR in May 1997, and KIBB flipped to a format they pioneered: "rhythmic oldies", in November 1997.
This boom screeched to a halt by the early 2010s, with many of the stations evolving into Mainstream or Rhythmic Top 40 (like KQMV or KMVQ San Francisco), or flipping to other formats, in part due to declining ratings and trying to adapt currents into this niche genre.
KHTP and KRBQ have since shifted in a more Classic Hip-Hop direction, positioning themselves as all-"Throwback" stations, while KSSX flipped to Mainstream Urban in May 2016.
This format combines the currents and recurrents of CHR stations with hot AC-like rotations, and a deep gold library that includes classic hip hop and dance/pop throwbacks dating back to the mid-1990s.
Today, stations in the Rhythmic AC format vary widely by market as to how much hip-hop and R&B product are included in the music mix, and how current-intensive they are.
Whereas the aforementioned KHTP and KRBQ have repositioned themselves as all-"Throwback" stations specializing in Classic Hip-Hop, WKTU, WMOV and other rhythmic hot ACs leaning heavily toward more modern pop and dance music.
