TelevisaUnivision (formerly known as Univision Communications) is a Mexican-American media company headquartered in Miami and Mexico City that owns American Spanish language broadcast network Univision and free-to-air channels in Mexico such as Las Estrellas, Canal 5, Foro, and NU9VE alongside a collection of specialty television channels and production studios. 45% of the company is held by the Mexican telecommunications and broadcasting company Grupo Televisa, which was a major programming partner for Univision until the company sold their content assets to Univision Communications in 2022.

Since its founding in the early 1960s as Spanish International Network (SIN), the United States' first Spanish language television network, the company has catered to Hispanic and Latino Americans. It is currently a multimedia conglomerate, with free-to-air and specialty, digital and audio networks, including 65 television stations, online and mobile apps and products.

Univision Communications Inc. was founded in 1962; 63 years ago (1962), as Spanish International Communications Corporation (parent of Spanish International Network) by Rene Anselmo, an American-Mexican TV executive Emilio Nicolas Sr., owner of KUAL-TV (now KWEX-DT) in San Antonio, and Mexican radio-TV magnate Emilio Azcárraga Vidaurreta, head of Telesistema Mexicano (now Televisa). They consolidated the operations of some independent Latino stations into a network. In 1987, Nicolas sold his part of the company to Hallmark Cards, and the name was changed to Univision Holdings. By 1992, Hallmark re-incorporated the company to Univision Communications.

On April 8, 1992, Hallmark sold Univision Communications to a group that included Los Angeles-based investor A. Jerrold Perenchio (a former partner in Norman Lear's Embassy Communications, who was outbid by the Hallmark-led consortium for the network in 1987), Emilio Azcárraga Milmo, and brothers Ricardo and Gustavo Cisneros (co-owners of Venezuelan broadcaster Venevision) for $550 million, in order to refocus its television operation efforts on cable provider Cencom Cable Associates, which it acquired the previous year for about $500 million. In order to comply with FCC rules on foreign ownership of television stations, the deal was structured to give Perenchio a controlling 75% interest in Univision's station group and 50% ownership of the network itself; Azcárraga and the Cisneroses held a 25% stake in the network and a 12.5% stake in the station group. The deal placed Univision under common ownership with competing cable channel Galavisión, which the Azcárraga-run Grupo Televisa owned at the time. The Cisneroses' ownership of stake in Univision Communications led to the broadcast of Venevision telenovelas from Venezuela, & eventually, to the co-production partnership of Venevision International and Univision Communications of telenovelas. The consortium ended up selling Univision Communications for $13.7 billion in 2007.

From September 1996 to April 2007, Univision Communications Inc. traded on the New York Stock Exchange under the symbol UVN.

In 2001, Univision Communications Inc. acquired USA Broadcasting, the station group of USA Networks, which included 13 full-power television stations. Most of these stations became part of a new network called TeleFutura, which it launched in 2002. Others joined Univision. In 2003, Univision completed the acquisition of Hispanic Broadcasting Corporation to form Univision Audio Network.

Prior to 2007, its headquarters was in the Century City neighborhood of Los Angeles.

In March 2007, Univision Communications was sold to Broadcasting Media Partners, a group led by Haim Saban that included Madison Dearborn Partners, Providence Equity Partners., TPG Capital, L.P., Thomas H. Lee Partners, and Saban Capital Group.
