iCloud is a cloud storage and cloud computing service from Apple Inc. announced on June 6, 2011 at the Apple Worldwide Developers Conference (WWDC). The service allows users to store data such as music files on remote computer servers for download to multiple devices such as iOS-based devices, and personal computers running OS X or Microsoft Windows. It also replaces Apple's MobileMe service, acting as a data syncing center for email, contacts, calendars, bookmarks, notes, to-do lists, and other data. As of 2012, the service has over 125 million users.

iCloud is the latest branding of Apple's cloud computing services. It has previously been branded as iTools in 2000, .Mac in 2002, and MobileMe in 2008.

MobileMe will be discontinued after June 30, 2012, with anyone who had an account before the unveiling of iCloud having their MobileMe service extended to that date, free of charge.

The official website, www.icloud.com, went live in early August for Apple Developers. On October 12, 2011, iCloud became available to use via an iTunes update. iCloud had 20 million users in less than a week after launch.

Steven Paul "Steve" Jobs (/ˈdʒɒbz/; February 24, 1955 – October 5, 2011) was an American businessman, designer and inventor. He is best known as the co-founder, chairman, and chief executive officer of Apple Inc. Through Apple, he was widely recognized as a charismatic pioneer of the personal computer revolution and for his influential career in the computer and consumer electronics fields. Jobs also co-founded and served as chief executive of Pixar Animation Studios; he became a member of the board of directors of The Walt Disney Company in 2006, when Disney acquired Pixar.

In the late 1970s, Apple co-founder Steve Wozniak engineered one of the first commercially successful lines of personal computers, the Apple II series. Jobs was among the first to see the commercial potential of Xerox PARC's mouse-driven graphical user interface, which led to the creation of the Apple Lisa and, one year later, the Macintosh. During this period he also led efforts that would begin the desktop publishing revolution, notably through the introduction of the LaserWriter and the associated PageMaker software.
