#5 Apple Ping, MobileMe and iWork

Apple had a long list of mercy killings this year. Among that, these three stand out. MobileMe was Apple’s first big foray in to cloud computing, a paid service, used to synchronize email, calendars, address books and more. But with people failing to receive email and the service suffering long outages, Apple decided to kill it, favoring iCloud.

Ping, Apple’s social networking service for music, was also killed this year due to its lac of integration with social networking sites.

iWork, the office suite of desktop applications from Apple was also killed in July 2012, forcing the users to embrace iCloud.

#4 Google Picnik

Picnik was an online photo editing service owned by Google. The shutting down of this service invited even petitions from people to stop it, but failed. The service offered users to import pictures from anywhere including Facebook, Flickr, Picasa albums, Yahoo image search and edit them. Many of the tools were offered free. However, the company in January 2012 had announced that they are closing down and some of their tools will be moved to Google+.

The site provided a refund to all premium members and offered some options to get some of their recent images as 'Picnik Takeout.' Picnik stopped allowing downloads of saved content and fully shutdown on April 19.
