TelevisaUnivision Replaces Ad-Sales Chief as TV Upfront Nears

TelevisaUnivision has replaced Tim Natividad with John Kozack as head of its ad-sales structure. Kozack has worked at the company for over two decades and has a deep understanding of its business. The move comes as the company prepares for the annual "upfront" marketplace, where TV companies sell commercial inventory. TelevisaUnivision's advertising revenue in the fourth quarter was $856 million, with a decline in the U.S. to $423 million.
