KBBT (98.5 FM, "98.5 The Beat") is a rhythmic contemporary radio station serving the San Antonio, Texas area, but is licensed to Schertz.

In 1998 Univision, seeking to tap into a unique Hispanic audience that was non-Spanish speaking, very contemporary and influenced by present-day trends, acquired KBUC and applied for a city of license change to Schertz and a frequency switch to 98.5 to cover the San Antonio Metropolitan area, which was approved in early April 2000.

On September 29, 2000, Univision officially launched KBBT, the company's first non-Spanish formatted outlet in San Antonio (outside of bilingual-speaking Tejano sister station KXTN-FM and later on, Active Rock turned Top 40 KLTO), where it shot up to number one in the ratings and has retained that position since its inception.

From the beginning, KBBT's musical formula, which started under its first program director J. D. Gonzalez, has centered on Hip-Hop/R&B hits, tailor-made for San Antonio, and in particular its large mix of teens, females, young adults, and bilingual Hispanic audiences.

In 2010, KBBT phased in Rhythmic pop tracks, but at the same time continued to stick to its hip-hop/R&B formula as it faces competition from Top 40/CHR rivals KXXM and a new version of KTFM.
