Video distribution site Hulu has taken itself off the market as its owners explore ways to work together to continue the success of the site. Burbank-based Walt Disney Co., News Corporation and Providence Equity Partners announced terminating the sales process in a posting Oct. 13 at the Hulu website blog. “Our focus now rests solely on ensuring that our efforts as owners contribute in a meaningful way to the exciting future that lies ahead for Hulu,” the statement said. Hulu, based in Santa Monica, was founded three years ago to distribute television shows from multiple networks via the web. The company put itself up for sale in June.
