Danny Villanueva, who co-founded Univision and helped turned it into a powerhouse in Spanish-language TV, has died. He was 77. His alma mater Mew Mexico State University said the exec died at a Ventura County hospital of complications from a stroke last week.

Following a career as a NFL kicker with the Los Angeles Rams and Dallas Cowboys in the 1960s, Villanueva co-founded Spanish daniel-l-villanueva_edited-1International Communications Corp., which later became Univision. He served in numerous top posts during his 25-year TV career developing and selling broadcast properties around the country and built KMEX-TV Los Angeles into one of the most profitable and influential Spanish-language stations in the U.S. He was a part owner of Univision when it was sold to Hallmark Cards and First Chicago Venture Capital in 1988.

The New Mexico native started at then-tiny KMEX as a sportscaster while still kicking for the Rams and KMEX_Logostayed with the station after being shipped to Dallas in 1965.

Villanueva also co-founded the investment firm Bastion Capital in 1992 and co-founded Rustic Canyon/Fontis Partners, an investment firm aimed at helping family businesses. During his career, he also held stakes in a pair Los Angeles pro soccer clubs: Major League Soccer’s Galaxy and the old NASL’s Aztecs.
