KSCI (channel 18) is a television station licensed to Long Beach, California, United States, serving the Los Angeles area. Owned by WRNN-TV Associates, the station airs programming from home shopping network Shop LC. KSCI's studios are located on South Bundy Drive in West Los Angeles, and its transmitter is located atop Mount Wilson. KSCI served as a multicultural independent station until June 2021.

The channel 18 allocation in Los Angeles was previously occupied by KCHU-TV, licensed to San Bernardino, which signed on the air on August 1, 1962, before it went off the air in June 1964. The station was owned by the San Bernardino Sun-Telegram. KSCI signed on the air on June 30, 1977, operating from studios in West Los Angeles, although still licensed in San Bernardino. It became a non-profit owned by the Transcendental Meditation movement (the call letters stood for Maharishi Mahesh Yogi's theoretical "Science of Creative Intelligence"). The station broadcast news stories, prerecorded lectures and variety shows with TM celebrities. KSCI's goal was to report "only good news"; sister stations were planned for San Francisco and Washington, D.C. The station manager was Mark Fleischer, son of Hollywood director Richard Fleischer.

In 1980, KSCI switched to a for-profit operation and earned $1 million on revenues of $8 million in 1985. In November 1985, the station loaned $350,000 to Maharishi International University in Iowa. By June 1986, the station's content began to consist of "a hodgepodge of programming" in 14 languages. They had dubbed themselves the "international station" and claimed to offer the most diverse ethnic television programming in the early 1980s. Almost all Iranian American television programs in the early 1980s were on KSCI.

In October 1986, the station was purchased by its general manager and an investor for $40.5 million.

In 1990, the station was sold to Intercontinental Television Group Inc., with programming being produced by Wahid Boctor of Arab American Television. In 1998, KSCI transferred its city of license from San Bernardino to Long Beach. In 2000, a Korean newspaper, The Hankook Ilbo, took over the International Media Group (IMG), which operated KSCI. IMG was re-launched as the AsianMedia Group, Inc., who purchased the station.

By 2005, the station was broadcasting seven English-language and three Spanish-language newscasts plus "local news programs in Vietnamese, Mandarin Chinese, and Korean" to 2.5 million Asian-American viewers in Southern California. In early 2005, KSCI changed its on-air branding to "LA18". ^{[citation needed]}

In October 2008, KSCI broadcast the Presidential debate along with translation in Mandarin and offered political analysis by their news staff. The broadcast was one of several that covered election events in Korean, Mandarin, Cantonese, Vietnamese and Filipino languages.

On January 9, 2012, KSCI, Inc. filed a voluntary petition for reorganization under Chapter 11 bankruptcy protection to the U.S. Bankruptcy Court for the District of Delaware. On August 11, 2012, KSCI was purchased by NRJ TV LLC, a company which has acquired smaller television stations in various U.S. cities for the possibility of placing their spectrum for auction once the Federal Communications Commission rolls out a voluntary spectrum auction for use for non-broadcast purposes in 2014.
