The network we know as Univision was founded by Raoul Cortez in 1955 as San Antonio's KCOR-TV. In 1961, the station was acquired by an investment group. http://broadcastengineering.com/products/Nab-nicolas-cortez-20060216/ Over time, KCOR-TV was turned into KWEX-TV, the Spanish International Network, and finally, Univision. http://www.sintv.org/sintv/history.html According to a Neilsen Study, Univision has a lion's share of the Hispanic market, with more Hispanics tuning in to its primetime offerings than those of 6 major networks, including ABC and Fox. http://corporate.univision.com/corp/en/univision.jsp The televnovelas (Spanish-language soap operas) that Univision airs are its programming and ratings mainstays. For the week of January 11, 2010, all ten "top Hispanic tv rankings" were Univision's telenovelas Sortilegio and En Nombre de Amor. http://blog.nielsen.com/nielsenwire/weekly-tv-ratings/
