The station is owned by Grupo Televisa.

XHUAA signed on in 1990; its original concessionaire was Radiotelevisora de La Rumorosa, S.A. de C.V.

Since 2003, the station is available nationwide on Sky México and Izzi Telecom, where it replaced Ponchivisión on both operators due to a mutual agreement.^[3]

Analog-to-digital conversion

By then-current Mexican law, XHUAA was suggested to start broadcasting digital television by January 1, 2010, although this station was allowed at its discretion to start broadcasting DTV before law required it to, and XHUAA-TDT had signed on in 2006. The original assignment was channel 20,^[5] but the chosen channel caused issues to land mobile services in Los Angeles, prompting the FCC in the United States to request a channel change.

Due to the conversion mandate, XHUAA-TV shut down its analog signal on May 28, 2013 and again on July 18, 2013, due to issues relating to elections.^[6] Tijuana was the first Mexican city to start the analog to digital conversion in Mexico.

XHUAA retained its virtual channel of 57 after October 2016 because channel 2 would create a channel conflict with KCBS-TV over portions of San Diego County. On March 6, 2020, it moved to the lowest number available in Tijuana, from channel 57 to channel 19.

Repeaters

XHUAA operates low-power repeaters in Tecate^[7] and Col. Playas de Tijuana.^[8]
