iBooks was announced alongside the iPad at a press conference in January 2010. The store itself, however, was released in America three days before the iPad with the introduction of iTunes 9.1. This was supposedly to prevent too much traffic on Apple's servers, as they have been overloaded with previous releases of the iPhone. On the day of its launch, on March 31, 2010, the iBooks Store collection comprised some 60,000 titles. On April 8, 2010, Apple announced that iBooks would be updated to support the
iPhone and
iPod Touch with
iOS 4. As a result, iBooks was not supported on first-generation iPhones and iPod Touches. On June 8, 2010, at the WWDC Keynote, it was announced that iBooks would be updated that month to read PDF files as well as have the ability to annotate both
PDFs and
eBooks. As of July 1, 2010, Apple expanded iBooks availability to
Canada. Upon its release for older devices running iOS 4, such as the
iPhone 3GS and
iPod Touch, iBooks received criticism for its slow performance. However, a July 19 update from Apple offered several improvements. On September 27, 2011, Apple expanded the premium store to
Ireland. On January 19, 2012, Apple announced the release of iBooks 2, which supported interactive
textbooks on the iPad; the release of iBooks 2 was accompanied by a new Mac app, iBooks Author. On October 23, 2012, Apple announced iBooks 3. On November 13, 2012, Apple was granted the patent "Display screen or portion thereof with animated graphical user interface" for page-turning animation. The page-turning animation was first filed for in December 2011 as ornamental design for a display screen. The patent's illustration shows three different images of a virtual page being turned. One with a corner of a page being turned slightly, the next image with the page halfway turned, and the third showing the page almost entirely turned over. The patent refers to
O'Reilly Media and FlippingBook companies that use page-turning animation in eBooks. which describes a novel method for gifting
e-books to friends. The patent describes how a user can select the appealing e-book snippet that will bring up a contextual menu containing an option to gift the media to another party. On November 15, 2013, Apple pushed version 3.2 of iBooks for iOS with a redesigned interface to match the "flat" style of
iOS 7, which dropped support for
iOS 6 and earlier versions. On the annual
WWDC in 2014, Apple unveiled that iBooks will be a pre-installed app in the next version of the operating system,
iOS 8, along with the
Podcasts app. On September 17, 2014, Apple bundled version 4.0 of iBooks for iOS with iOS 8.0. This includes slight changes with the bookstore button (into a persistent navigation bar at the bottom), grouping of books by series in the bookshelf, Auto-night mode theme, as well as small changes to the underlying rendering engine. On October 20, 2014, Apple bundled version 4.1 of iBooks for iOS with iOS 8.1. On January 24, 2018, Apple renamed iBooks to Books in the iOS 11.3 beta. As well as in macOS 10.13.4 beta iBooks to Books on March 5, 2018. It was renamed back to iBooks in a next intermittent 10.13.4 macOS beta, showing some uncertainty about the marketing decision. In early 2019, Apple renamed the app Apple Books. On September 19, 2019, Apple included an Audiobooks app with
watchOS 6 to play from the Apple Books Audiobook store.
Formats The supported
e-book formats of Apple Books are
