On December 18, 1962, Broadcasting Service of America filed an application for a construction permit to build a new TV station on channel 40 licensed to Guasti.

William A. Myers, the principal of Broadcasting Service of America, was noted as concerned by the lack of local programming on television in a 1965 report on KBSA being authorized to locate atop Mount Wilson.

[3] With little fanfare, channel 46 finally signed on August 16, 1972, five days after the FCC granted KBSA program test authority; it primarily broadcast in Spanish.

A year later, KBSA was sold, first in a minority stake and then entirely,[5] to the Berean Baptist Church; TBN would buy KLXA (channel 40) in Fontana and eventually renamed that station KTBN.

[11] Three months later, however, Berean announced it had sold the station to a different concern: Metropolitan Broadcasting Company, owned by Robert F. Beauchamp, in a proposed $1.55 million transaction.

[16] In preparation for returning to the air, on November 28, 1983, the call letters were changed to KIHS-TV; the seven-year silence was broken on April 21, 1984—the day before Easter Sunday.

[20] Harry G. John, a major philanthropist involved with De Rance, had been dismissed after mismanagement of the foundation by spending millions on the television operations.

[4] In September 1986, the Home Shopping Network (HSN) acquired KIHS-TV for $35 million, putting an end to De Rance's plans to expand its Catholic programming nationwide.

By 1998, after HSN bought the Universal Pictures TV assets from Seagram, Silver King Broadcasting became USA Broadcasting and plans were to switch all of its stations to a new general entertainment independent format known as "CityVision" featuring both locally-produced programming and live sports along with syndicated drama and sitcom reruns, movies and syndicated cartoons.

Stations in Miami (as "WAMI 69"), Boston (as WHUB "Hub 66"), Atlanta (as WHOT-TV "Hotlanta 34"), and Dallas–Fort Worth (as "K-Star 49") had all switched to the format.

The Walt Disney Company was the leading candidate to buy the stations, which would have made channel 46 a sister to ABC's flagship KABC-TV.

However, Univision Communications outbid Disney and in January 2002 used channel 46 (whose call letters were changed to KFTR-TV) and all but three of USAB's stations to become the nucleus for its new second network TeleFutura (now known as UniMás).
