ITunes Store
The iTunes Store, originally the iTunes Music Store, is a software-based online digital media store operated by Apple Inc. It opened on April 28, 2003, and has been the largest music vendor in the United States since April 2008,〔(【引用サイトリンク】url=http://www.apple.com/pr/library/2008/04/03itunes.html )〕 and the largest music vendor in the world since February 2010. It offers over 43 million songs, 700,000 apps, 190,000 TV episodes and 45,000 films as of September 12, 2012.〔 The iTunes Store's revenues in the first quarter of 2011 totalled nearly US$1.4 billion; by February 6, 2013, the store had sold 25 billion songs worldwide.〔
While most downloaded files initially included usage restrictions enforced by FairPlay, Apple's implementation of digital rights management (DRM), iTunes later initiated a shift into selling DRM-free music in most countries, marketed as iTunes Plus. On January 6, 2009, Apple announced that DRM had been removed from 80% of its music catalog in the US. Full iTunes Plus availability was achieved in the US on April 7, 2009, coinciding with the introduction of a three-tiered pricing model; however, television episodes, many books, and films are still FairPlay-protected. As of June 2013, the iTunes Store possesses 575 million active user accounts, and serves over 315 million mobile devices, including Apple Watches, iPods, iPhones, Apple TV and iPads.〔(【引用サイトリンク】title=iPhone 5 announcement: 3 important things to watch )〕〔
==History==
Before the iTunes Store, most of the online music was download through websites like Napster.〔(【引用サイトリンク】title=Steve Jobs on the iTunes Music Store: The Unpublished Interview )〕 Steve Jobs expressed concern that people were illegally obtaining music because it was the only option they had. In 2002, Steve Jobs made an agreement with the five major record labels to offer their content through iTunes.〔 The iTunes Store was introduced by Steve Jobs at a Worldwide Developer's Conference to give music listeners a legal alternative to peer-to-peer file sharing networks.〔(【引用サイトリンク】title=Steve Jobs’ Music Vision )〕 When it opened, it was the only legal digital catalog of music to offer songs from all five major record labels. At first, it was only available on Mac OS and the iPod.〔(【引用サイトリンク】title=Apple - Press Info - Apple Launches the iTunes Music Store )〕
