Exabyte

uding all audio, video recordings, and text/books) was about 12 exabytes of data.[26] The 2003 Berkeley report stated that in 2002 alone, "telephone calls worldwide on both landlines and mobile phones contained 17.3 exabytes of new information if stored in digital form" and that "it would take 9.25 exabytes of storage to hold all U.S. [telephone] calls each year".[21] International Data Corporation estimates that approximately 160 exabytes of digital information were created, captured, and replicated worldwide in 2006.[27] Research from University of Southern California estimates that the amount of data stored in the world by 2007 was 295 exabytes and the amount of information shared on two-way communications technology, such as cell phones in 2007 as 65 exabytes.[28][29]

Library of Congress

The content of the Library of Congress is commonly estimated to hold 10 terabytes of data in all printed material. Recent estimates of the size including audio, video, and digital materials start at 3 petabytes[30] to 20 petabytes. Therefore, one exabyte could hold a hundred thousand times the printed material, or 500 to 3,000 times all content of the Library of Congress.

Google

In 2013, Randall Munroe compiled published facts about Google's data centers, and estimated that the company has about 10 exabytes stored on disk, and additionally approximately 5 exabytes on tape backup.[31] The company has refused to comment on Munroe's estimate."[32]
