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.iCloud was announced on June 6, 2011, at the Apple Worldwide Developers Conference (WWDC). Apple announced that MobileMe would 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.The iCloud.com domain and registered trademark were bought from a Swedish company called Xcerion, who rebranded their service to CloudMe.CloudMe still controls major domains like iCloud.de, iCloud.fr and iCloud.es. A class action lawsuit by customers unhappy over the transition from MobileMe to iCloud was filed in early May 2012.

The first official mention of iCloud from Apple came on May 31, 2011, when a press release announced that it would demonstrate the service at the WWDC on June 6, 2011. A banner hung at the Moscone Center for WWDC revealed the iCloud logo five days before the official launch. In the WWDC 2011 keynote speech, Apple announced iCloud will replace MobileMe services and that the basic iCloud service will be free of charge.
