The film was released for the first time on DVD on October 17, 2000, in a two-pack with its first sequel Toy Story 2. The same day, a 3-disc "Ultimate Toy Box" set was released, featuring Toy Story, Toy Story 2, and a third disc of bonus materials with Toy Story in a 35 mm Widescreen print and Toy Story 2 only being in FullScreen. The twin-pack release was later released individually on March 20, 2001 with the film available in both Widescreen and pan-and-scan. The DVD-pack, U.T.B. set and the original DVD use the 35 mm print of the film to create the copies, rather than using the original files to encode the movie directly to video. The DVD two-pack, the Ultimate Toy Box set, the Gold Classic Collection VHS and DVD, and the original DVD were all put in the Disney Vault on May 1, 2003. On September 6, 2005, a 2-disc "10th Anniversary Edition" was released featuring much of the bonus material from the "Ultimate Toy Box", including a retrospective special with John Lasseter, a home theater mix, as well as a new digital Widescreen picture with the 35 mm Fullscreen version being retained. This DVD went back in the Disney Vault on January 31, 2009 along with Toy Story 2. The 10th Anniversary release was the last version of Toy Story to be released before taken out of the Disney Vault lineup along with Toy Story 2. Also on September 6, 2005, a Universal Media Disc of Toy Story featuring some deleted scenes, a filmmakers reflect and a new "Legacy of Toy Story" was released for the Sony PlayStation Portable.
