HBO‘s longtime chief technology officer Robert Zitter is stepping down as of March 31 and will handle special projects at the premium network until the end of next year. Otto Berkes has been named the company’s new EVP Technology and Chief Technology Officer, responsible for overseeing consumer technology, distribution, origination, production operations, engineering and IT. He joined HBO in 2011 as SVP Digital Products, coming from Microsoft, where he was one of the four original founders of Xbox.

Zitter’s career has included spearheading the introduction of digital compression technology, the development and launch of HBO HD and HBO On Demand and is one of the founders of HBO’s businesses in Latin America, Asia and Europe. “There are very few names that come to mind who have had as significant an impact on our industry as Bob Zitter,” said HBO president and COO Eric Kessler. “His accomplishments and innovation have helped transform not just the business at HBO but the entire landscape.” Zitter was inducted into The Cable Television Hall of Fame in 2006 and is a recipient of the NCTA’s Vanguard Award for his leadership in science and technology. He also served on the FCC’s Technology Advisory Committee and as a director of the North American Broadcasters Association.
