text: why do univision shut dowm?   univision dates its origins to 1961, when kwex began broadcasting to the hispanic community in san antonio, texas. that station was part of the spanish international network (sin), univision's predecessor. it was owned by telesistema mexicano, mexico's largest private broadcaster and the forerunner of televisa.  in 1986, the federal communications commission forced televisa to sell sin because of federal laws against foreign ownership of american tv stations. sin was sold to hallmark cards and renamed univision. under hallmark's ownership, about half of its programming was rebroadcasts of telenovelas and other programming from televisa, and half was original programming produced in miami. when hallmark sold univision in 1992, its present owners cut a third of the miami staff and reverted to a schedule based mostly on televisa programs. henry cisneros, a former u.s. department of housing and urban development official under president bill clinton, became president of univision.  the company's stock has been traded on the new york stock exchange since 1996; it became part of the s&p 500 in february 2001.  in 2002, univision entered into a local marketing agreement (lma) with raycom media to operate two television stations in puerto rico: wlii in caguas and wsur-tv in ponce. at the time, wlii had a longtime lma with another puerto rican station, wste, which univision honored. both wlii and wsur-tv were sold to univision in 2005.  in late 2004, a feud began between univision's chairman, 78-year old italian entertainment guru jerrold perechino, and the 32-year old head of televisa, emilio azcarraga jean. the dispute is about univision's continual censoring of televisa's programming, and failure to pay for transmission of televisa prodcued sports and specials. the feud has intensified to the point where televisa's most famous stars have been banned from appearing on any univision-produced shows and specials. in addition, televisa has also has filed a lawsuit against univision for breach of contract.  in recent years, univision has also lost several key on air personalities to telemundo, including long time weekend news anchor maria antonieta collins, and news anchor maria celeste arraras.  on february 9, 2006 univision communications confirmed that it is putting itself up for sale. rupert murdoch, chairman of the news corporation, has stated that his company is considering buying univision. other expected bidders are time warner, cbs, walt disney, grupo televisa of mexico and several private equity firms.
