On March 1, 1985, channel 2 became known as KNMZ-TV and began running cartoons, old sitcoms and other shows that had previously aired on KNAT-TV (UHF channel 23), which had recently gone dark (it returned the next year as a TBN affiliate).

KNMZ-TV was sold the next year to New Mexico Media Limited License Holdings, then in late 1987 to Las Vegas-based Sunbelt Communications Company. The deal closed in early 1988 and the format stayed the same, then on September 4, 1989 the station changed call letters to KKTO-TV. The "2" logo and the two fingers are resembles the one used by WKAQ-TV in San Juan from 1993 to 1997.

In the fall of 1992, after being unable to turn a profit as an independent station and to focus on its profitable NBC affiliates in Nevada, Sunbelt took KKTO-TV dark, with the station's strongest programming (including The Disney Afternoon) moving to KGSW-TV (channel 14). Later that fall, the channel 2 license was sold to the Providence Journal Company, which moved the KGSW intellectual unit to channel 2 and surrendered its old channel 14 license to the Federal Communications Commission (FCC) on April 5, 1993. (Channel 14 is now occupied by KLUZ-TV, a Univision affiliate.) Two months earlier, on February 2, 1993, the station's call letters were changed to KASA-TV, based on the Spanish word casa ("home"). Raycom Media purchased KASA-TV and NBC affiliate KHNL (VHF channel 13) in Honolulu in 1999. On July 27, 2006, Raycom announced that LIN Media, owner of CBS affiliate KRQE (channel 13), was purchasing KASA for $55 million. The takeover took effect on September 15, 2006.

The Fox affiliation was moved down as a subchannel of KRQE on channel 13.2 and KASA switched to Telemundo on January 18, 2017.
