Hopkinton, Mass.—The amount of digital information increased to 800 billion gigabytes in 2009, an increase of 62% compared with 2008, according to "The Digital Universe Decade," an IDC study sponsored by EMC Corp. This growth occurred even during the Great Recession.

This amount of digital information is equal to what would be produced by every person on earth "tweeting" continuously for a century, according to the study. The study anticipates that the amount of digital information will increase by a factor of 44 between 2009 and 2020.

The study also predicts that one-third of digital information created in a year will either "live in or pass through the cloud" and require enhanced security and storage. Enterprises will be responsible for the storage, protection, and management of 80% of the digital universe, according to the study.
