Run out of studios in both New York City and Miami, UNIVISION has local stations on over 50 American markets. Founded in San Antonio, Texas in 1955 as KUAL-TV, the network soon gained footholds in the Los Angeles and New York City markets and came to be known as the Spanish International Network. In 1987, owner Emilio Nicholas Sr. sold his interest to Televisa and the Hallmark Company. The new ownership rebranded the station as UNIVISION. In 1993, the network was bought by Jerry Perenchio, who held controlling interest until 2006, when it was purchased by the Broadcast Media Partners. UNIVISION holds the distinction of being the first Spanish-speaking television station to operate within the continental U.S. and the first to broadcast its signal in HD.
