The Kinneloa Fire was a destructive wildfire in October 1993 in Los Angeles County, California. The fire burned 196 structures in the San Gabriel Mountains foothill communities of Altadena, Kinneloa Mesa, and Sierra Madre. At the time, it was the 12th most destructive wildfire in recorded California history, and though it has since fallen well out of the top 20 statewide, it remains one of the most destructive wildfires in the history of Los Angeles County. The fire resulted in one fatality and a multitude of minor injuries: one person died of pneumonia complicated by smoke inhalation, and two indirect deaths resulted from debris flows in the burn area more than four months later. The fire began as an escaped campfire and was driven by a combination of extremely dry and flammable fuels, strong Santa Ana winds, and rugged topography. Nearly all of the structure losses occurred on the first day of the wildfire, and more favorable weather along with the efforts of more than 2,000 firefighters soon confined the fire to the mountainous backcountry of the Angeles National Forest until it was completely contained on November 1. The Kinneloa Fire was one of the most significant of a rash of wildfires that broke out across Southern California in late October 1993, most of them driven by the same episode of Santa Ana winds. It burned simultaneously alongside the Laguna Fire in Orange County, the Green Meadow Fire in Ventura County, the Ortega Fire in Riverside County, and several others.

It is owned by Meruelo Broadcasting alongside Spanish independent KWHY-TV (channel 22); the two stations share channel 4 for their broadcasts. KBEH and KWHY share studios on West Pico Boulevard in the Mid-City section of Los Angeles and transmitter facilities atop Mount Wilson. Channel 63 was originally allocated to Oxnard and began broadcasting in 1985 as KTIE-TV, a local independent station for the Ventura County area. It struggled through its original ownership and was sold to Meshulam Riklis in 1988. KTIE-TV was renamed KADY-TV, after Riklis's daughter, Kady Zadora. General manager John Huddy acquired the station in 1991 but left a financial mess in his wake, leading to a court-appointed receivership in 1996. The station stabilized under its next owner, media broker Brian Cobb. In 2004, KADY-TV built a booster increasing its Los Angeles coverage and was sold to Bela Broadcasting, which switched it to Spanish-language programming. Since the sale, KBEH has primarily been a Spanish-language station under several owners, with program sources including MTV Tres, the short-lived CNN Latino, and its present programming from the Universal Church of the Kingdom of God.
