DVD release
The DVD release of season one was released after the season has completed broadcast on television. It has been released in Regions 1, 2 and 4. As well as every episode from the season, the DVD release features bonus material such as audio commentaries on some episodes from the creator and cast, deleted scenes, gag reels and behind-the-scenes featurettes. The words "The WB Presents" were printed on the packaging before the "One Tree Hill" title, although they were not included on international releases as The WB was not the broadcaster.
