The station came on air in April 1965 as XEMMM-AM, named for its owner, Mario Marcos Mayans. 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. 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.
