On the heels of Univision’s announcement that it may consider putting its TV, digital and radio assets on the block, one of the company’s lead investors will spend much of the week in Sun Valley chatting up potential buyers. Univision backer Haim Saban, who along with a group of private equity investors purchased the Spanish-language media company in 2007 for $13.7 billion, arrived in the Idaho resort town yesterday for the annual Allen & Company confab, where he’ll look to drum up interest from the likes of Disney, Viacom and Discovery.
