Why Pink Floyd...? was a re-release campaign of Pink Floyd's back catalogue, released in three stages over 2011–12. Under the campaign, multiple forms of the band's material were released, with new remasters and unreleased tracks. The albums were available in three different configurations: "Discovery", "Experience" and "Immersion". The "Immersion" boxsets of The Dark Side of the Moon and Wish You Were Here featured 5.1 surround sound mixes of the original albums, while that of The Wall did not. Wish You Were Here was also released in an SACD version. A new best-of album, titled A Foot in the Door – The Best of Pink Floyd was released, as well as Sampler, a Best Buy exclusive compilation.
Phase 1 of the Why Pink Floyd...? campaign began on 26 September 2011 with the release of The Dark Side of the Moon "Experience", "Immersion" and vinyl editions; a remastered re-release of all 14 studio albums, a Discovery box set containing all 14 with a booklet, and a Sampler.
Phase 2 of the campaign began on 7 November 2011 with the release of the Wish You Were Here "Experience", "Immersion", SACD and vinyl editions; a new "best of" album entitled A Foot in the Door – The Best of Pink Floyd; and continued with the release of a Pink Floyd iOS app on 14 November 2011.
Phase 3 of the campaign began on 27 February 2012 with the release of The Wall "Experience", "Immersion" and vinyl editions.
