800 AM is a Mexican clear-channel frequency on which XEROK-AM in Ciudad Juárez is the dominant Class A station.

History
The station came on air in April 1965 as XEMMM-AM, named for its owner, Mario Marcos Mayans. The Mayans family owned Cadena Baja California (CBC, later Grupo Cadena), which ran XEMMM from 1965 to 2022. The station initially broadcast during the daytime only.

XEMMM joined ESPN Radio in late 2002, replacing XETRA, which had changed from sports radio to adult standards some months earlier. In 2003, the call sign changed to XESPN. (The XEMMM calls were moved to a station Cadena Baja California then owned in Mexicali, now XEMMM-AM 940.) In 2009, ESPN Radio moved to sister FM station XHMORE while XESPN joined ESPN Deportes Radio.

On November 1, 2010, CBC ceased sports programming on XESPN and adopted a news/talk format programmed by Grupo Imagen. ESPN Deportes Radio is now available in the San Diego-Tijuana border region on XESS-AM 620. Imagen's news programming was later replaced on XESPN with programming from Radio Fórmula.

On May 22, 2022, XESPN-AM went off the air, and its programming was moved to online only. It did not begin coming back on the air until April 2023, after the Cadena stations were sold to a consortium related to Tijuana news website Esquina 32.
