From Univision to Telemundo and Galavision, Spanish-language media has become commonplace in televisions across the United States. The nation’s largest Spanish-language TV service provider, Univision, recently celebrated its 70th anniversary last year. Mexican media executive Raoul Cortez founded KCOR-AM radio in San Antonio in 1946 and later expanded his broadcast empire to launch KCOR-TV in 1995. The book Live from America : How Latino TV Conquered the U.S. details the powerful figures who worked behind the scenes to make Spanish-language media successful. Author Javier Marín said the role of Spanish media in a political campaign was first documented in the election of San Antonio Congressman Henry B. Gonzalez.
