Cover Flow

Cover Flow is an animated, three-dimensional graphical user interface element that was integrated within the Macintosh Finder and other Apple Inc. products for visually flipping through snapshots of documents, website bookmarks, album artwork, or photographs.

Cover Flow is browsed using the on-screen scrollbar, mouse wheel, gestures, or by selecting a file from a list, which flips through the pages to bring the associated image into view. On iPod and iPhone devices, the user slides their finger across the touch screen or uses the click wheel.

Apple discontinued the use of Cover Flow after settling a patent suit against Mirror Worlds. It is now absent on the Mac in everything other than Finder with OS X El Capitan. In macOS Mojave, a completely different Gallery view feature replaces Cover Flow in Finder. It was removed from iOS in 2015 with the release of iOS 8.4, which replaced the Music app with Apple Music.

History

Cover Flow was conceived by artist Andrew Coulter Enright and originally implemented by an independent Macintosh developer, Jonathan del Strother. Enright later named the interaction style ''fliptych'' to distinguish it from the particular Cover Flow implementation.

Cover Flow was purchased by Apple Inc. in 2006, and its technology was integrated into its music application, iTunes 7.0, which was released September 12, 2006. The name was previously "CoverFlow" without a space.

The last release of Steel Skies’ stand-alone application, version RC1.2, was released on September 10, 2006, and freely distributed until the end of the next day only; however, it remains available for download from MacUpdate.

On January 9, 2007, when Apple announced the iPhone, it was announced that it would incorporate Cover Flow technology.

During the WWDC Keynote on June 11, 2007, Steve Jobs announced that Cover Flow would be added as a view option in Mac OS X Leopard's Finder.

On September 5, 2007 Apple announced that Cover Flow would be utilized in the third generation iPod nano as well as the new iPod classic and iPod Touch models. Cover Flow was integrated into the fourth-generation iPod nano by the use of an accelerometer which accesses Cover Flow when the iPod nano is turned horizontally on its side.

On March 14, 2008, Mirror Worlds LLC sued Apple for infringing on its patents (nos. 6006227, 6638313, 6725427, and 6768999) (Mirror Worlds, LLC, vs Apple, Inc; Texas Eastern District Court)

On February 24, 2009, Cover Flow was also included with the public beta of Safari 4, with the final version of Safari 4, released on June 8, using Cover Flow to browse history, bookmarks, RSS feeds, Bonjour, and the Address Book.

In April 2010, Apple was granted US design patent D613,300 on the Cover Flow interface.

On October 1, 2010, Apple was ordered to pay $625.5 million to Mirror Worlds LLC for infringing utility patents relating to Cover Flow. On April 4, 2011, Judge Davis reversed the judgement.

With the release of version 11 of iTunes, Cover Flow was removed from the iTunes interface.

iOS 7 saw Cover Flow replaced by Album Wall. This feature shows tiles of album art in rows when the device is in landscape. This feature was removed with the release of iOS 8.4 on June 30, 2015.

In macOS Mojave, Cover Flow was removed from Finder and replaced by gallery view.
