Spanish International Network
Univision originally began in 1962 as the Spanish International Network, with KCOR-TV (channel 41; now KWEX-DT) in San Antonio and KMEX-TV (channel 34) in Los Angeles, forming the cornerstone of the network.
Prior to 1986, Televisa filed a US trademark patent of "Univision"; this unused logo dates back to 1978, making it the very first logo of Univision.
In 1986, Spanish International Network rebranded as Univision, after the network became owned under a joint venture between Hallmark Cards and Mexican broadcaster Televisa; its logo at the time, was similar in resemblance to the logo used by Televisa, who distributes much of its programming for broadcast on Univision in the United States.
Univision unveiled a new look on October 15, 1989. The logo is on-air from January 1, 1990 to December 31, 2012.
On October 17, 2012, Univision unveiled a new look, which debuted on-air on January 1, 2013.
