The parent companies of Fox TV, ABC, and NBC may have a new partner in operating Hulu, the video website that streams TV episodes online to U.S. audiences. Bloomberg News reported on Wednesday that Time Warner Cable is considering taking a stake in the online video company, becoming Hulu's fourth partner. Bloomberg said that the three current partners -- NBC must effectively act as a silent partner in any negotiations per parent Comcast's agreement with the FCC when it acquired the network -- are also being wooed by other possible buyers. Other media companies are also said to be interested in taking a stake in the satellite company, including Amazon, Yahoo, Chernin Group and Guggenheim Partners.
