The move is the latest by the Google Inc-owned video service to increase the range of video clips through which it can sell advertising.
Currently, most of the clips are uploaded by users, which advertisers are reluctant to advertise alongside because they are frequently unprofessionally produced and may have inappropriate material.
Some Time Warner-owned programing is already available on YouTube including HBO and CNN International outside the United States.
The new deal will allow YouTube users in the United States to watch short clips of television shows like "Gossip Girl" and the "Ellen DeGeneres Show" as well as some Warner Brothers movies.
As part of the deal YouTube will also be integrating the Time Warner player into the site.
