Why Pink Floyd...? was a release campaign of Pink Floyd's back catalog, released in three stages over 2011–2012. Under the campaign, multiple forms of the band's material was released, with new remasters and unreleased tracks. The albums were available in three different configurations: "Discovery", "Experience" and "Immersion".

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.
