The App Store is a digital distribution platform for mobile apps on iOS, developed and maintained by Apple Inc. The service allows users to browse and download applications that are developed with Apple's iOS SDK. The apps can be downloaded directly to iOS devices such as the iPhone smartphone, the iPod Touch handheld computer and the iPad tablet computer, or onto a personal computer via iTunes. The App Store has more than 1.4 million apps〔 and more than 100 billion copies of apps have been downloaded.〔Nathan Ingraham (June 9, 2015). ("Apple's App Store has passed 100 billion app downloads" ). ''The Verge''.〕 Apps may be downloaded for free or for a set cost, and they may include in-app monetization (costs levied from sale of virtual goods and/or advertising). Apple takes 30 percent of all revenue generated through apps, and 70 percent goes to the app's publisher.〔(Apple's App Store: An economy for 1 percent of developers ). CNET. Retrieved 4 July 2015〕 ==History== In the beginning, the NeXT Computer and the object oriented development tools and libraries it relied on, were used to develop the first electronic "app store": the Electronic AppWrapper in the early 1990s. This same technology concept was used to create the iTunes music store and later the iOS App Store. The iPhone App Store opened on July 10, 2008, via an update to iTunes. It allowed Apple to control the quality of apps for the first time and to introduce a charge on top of the basic cost of the app. On July 11, the iPhone 3G was launched and came pre-loaded with iOS 2.0.1 with App Store support; new iOS 2.0.1 firmware for iPhone and iPod Touch was also made available via iTunes. , there are at least 1,100,000+ third-party apps officially available on the App Store.〔 As of January 18, 2011, the App Store had over 9.9 billion downloads, which was announced via the company's "10 Billion App Countdown".〔("10 Billion App Countdown" ) Apple January 14, 2011.〕 At 10:26 am GMT on Saturday, January 22, 2011,〔(10:26 AM GMT on Saturday, January 22, 2011 ) setteB.IT January 22, 2011.〕 the 10 billionth app was downloaded from Apple App Store. As of July 2011, 200 million iOS users downloaded over 15 billion apps from its App Store.〔 The mean revenue per application is estimated to be US$8,700, although data is not publicly available.〔(【引用サイトリンク】title=Full Analysis of iPhone Economics – it is bad news. And then it gets worse )〕 In 2015, it was estimated 1,260 developers would make at least $ 1 million. As of May 2011, Apple approved its 500,000th app and 37 percent of all apps are free with an average price of $3.64. The distribution of price follows a power law distribution (the Zipf–Mandelbrot law). Prices can be freely chosen by sellers at multiples of US$1 minus 1 cent (99¢, $1.99, and so on). After the success of Apple's App Store and the launch of similar services by its competitors, the term "app store" has been adopted to refer to any similar service for mobile devices. However, Apple applied for a U.S. trademark on the term ''App Store'' in 2008 which was tentatively approved in 2011. Later, in June 2011, U.S. District Judge Phyllis Hamilton, who was presiding over Apple's case against Amazon, said she would "probably" deny Apple's motion that seeks to bar the Web retailer from using the "App Store" name. Later on July 6, Apple was denied preliminary injunction against Amazon's Appstore by a federal judge. The term ''app'' has become a popular buzzword; in January 2011, ''app'' was awarded the honor of being 2010's "Word of the Year" by the American Dialect Society.〔(【引用サイトリンク】title=Apple Certifications )〕 Apple does not hold a trademark on, or claim exclusive rights to the term ''app,'' which has been used as shorthand for "application" since at least the mid-1990s and in product names since at least 2002, for example Google Apps (introduced in 2006).〔(【引用サイトリンク】title=Google Launches Hosted Communications Services )〕 On October 20, 2010, Apple announced the Mac App Store which was eventually launched on January 6, 2011. It is similar to the one for iOS devices, only it has applications designed for Mac computers. The Mac App Store is only accessible by using Mac OS X 10.6.6 "Snow Leopard" or later. The App Store is accessible from the iPhone, iPod Touch and iPad via an iOS application by the same name. It is also the only way to directly download native applications onto an iOS device without jailbreaking the device. Web applications can be installed on these devices, bypassing the App Store entirely, but they tend to have inferior functionality. The store is also accessible through iTunes, and then on any operating system for which iTunes is provided (OS X and Windows). In February 2011, Apple announced its new subscription-based service, which will allow publishers the freedom to set the length and price of subscriptions. Previously, new magazine or news releases were sold on a per release basis. The new service allows publishers to sell content directly through their apps, allowing users to receive new content over specified periods of time. Furthermore, Apple will begin allowing publishers to not only distribute and/or sell their applications from iTunes, where revenues will continue to be shared (70 percent for the publisher, 30 percent for Apple), but also allow them to distribute their subscriptions directly from their websites, where no revenue will be shared with Apple. During Apple's 2012 Worldwide Developer's Conference, Apple CEO Tim Cook announced that the App Store boasts 400 million accounts with registered credit cards, 650,000 available apps to download as well as "An astounding 30 billion apps" downloaded from the app store.〔Indvik, Lauren. June 11, 2012. "App Store Stats: 400 Million Accounts, 650,000 Apps." http://mashable.com/2012/06/11/wwdc-2012-app-store-stats/〕 Following the launch of the iPhone 5, Apple updated the UI of the App Store, as well as the iTunes Store and iBookstore, in iOS 6.〔(Picture of the new App Store UI running on iPhone 5 )〕 This was the first major overhaul since the App Store launch in 2008. On January 7, 2013, Apple announced that there have been over 40 billion apps downloaded from their iOS App Store, with almost half of those downloads coming in 2012.〔Lomas, Natasha. January 7, 2013. "Apple App Store: 40B Downloads And Counting; 2B+ In December, ~20B In 2012." http://techcrunch.com/2013/01/07/apple-app-store-40bn-downloads-and-counting-2bn-in-december-20bn-in-2012/〕 On February 1, 2013, Apple informed developers that they could begin using appstore.com for links to their apps.〔(Apple: Don't Visit Appstore.com ). Business Insider (February 4, 2013). Retrieved on July 30, 2013.〕 In September 2013, Apple announced at its Worldwide Developers Conference the addition of a Kids category to the App Store alongside the launch of iOS 7. The category is broken down by age range and apps aimed at the under-13 set are required to follow the Children’s Online Privacy Protection Act (COPPA) requirements. As of the end of 2013, App Store users spent over $10 billion in 2013, users downloaded almost three billion apps in December 2014 making it the most successful month in App Store history, and App Store developers have earned over $15 billion since the inception of the App Store.〔(【引用サイトリンク】title=Apple Reports on the App Store )〕 On November 17, 2014, Apple updated the App Store so that all apps that have no charge to download are labeled "GET" instead of the previous "FREE" and apps that include microtransactions include smaller subtext that says "In-App Purchases".〔(Apple Replaces “FREE” Label with “GET” on App Downloads in iTunes App Store ). November 19, 2014〕 In June 2015, the Apple announced there have been over 100 billion apps downloaded from the App Store. In September 2015, it was announced that there were apps that used , malicious code from another party.〔(【引用サイトリンク】url=http://mobile.reuters.com/article/idUSKCN0RK0ZB20150920 )〕 Some of the bigger apps that had the code are Angry Birds 2, CamCard, TinyDeal.com, among others. Apple has stated that is will make the Xcode easier to download by allowing local servers to be established that will allow app developers to access the Xcode more easily. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「App Store (iOS)」の詳細全文を読む スポンサード リンク
