PASADENA, Calif. (July 24, 2009)--Hulu might not be free forever.

Walt Disney Chief Executive Bob Iger told a technology conference outside Los Angeles that the online video streaming site might one day charge for its content.

He cited statistics that state people are willing to pay $5 an hour to watch movies, 75 cents an hour to read books, magazines and newspapers, and 25 cents for every hour of Internet use.

Disney, NBC and News Corp. own Hulu.
