Reading From 2000 to 2003, more information is expected to be generated on Earth than in the past 300, 000 years. In 1999 alone, the global database grew by 1.5 exabytes to about 12 exabytes or 12 million terabytes, with one terabyte equals about the volume of one million books. This was calculated by scientists from the School of Information Management & Systems (SIMS) at Berkeley University of California in a recently published study.

The subject of the study was the globally existing data volumes, which exist in printed form and are stored on optical or magnetic media or broadcast on television and radio. The researchers found that only 0.003 percent of the world's available data is on paper. Most of the information is stored in digital form on special data media. New data are increasingly being generated in digital form, which, according to the scientists, will trigger a boom in demand for storage media and data management concepts. Private households are now also working hard to increase the volume of data thanks to new technical options such as PC, Internet and e-mail.

The study entitled How Much Information can be found on the SIMS web pages.
