[|How Much Information? 2003 - Executive Summary]

 * Print, film, magnetic, and optical storage media produced about 5 exabytes of new information in 2002.Ninety-two percent of the new information was stored on magnetic media, mostly in hard disks.


 * We estimate that the amount of new information stored on paper, film, magnetic, and optical media has about doubled in the last three years.


 * Information flows through electronic channels -- telephone, radio, TV, and the Internet -- contained almost 18 exabytes of new information in 2002, three and a half times more than is recorded in storage media. Ninety eight percent of this total is the information sent and received in telephone calls - including both voice and data on both fixed lines and wireless.
