The world's technological capacity to receive information through one-way broadcast networks was 432 exabytes of (optimally compressed) information in 1986, 715 (optimally compressed) exabytes in 1993, 1.2 (optimally compressed) zettabytes in 2000, and 1.9 zettabytes in 2007 (this is the information equivalent of 174 newspapers per person per day).[4] The world's effective capacity to exchange information through two-way telecommunication networks was 281 petabytes of (optimally compressed) information in 1986, 471 petabytes in 1993, 2.2 (optimally compressed) exabytes in 2000, and 65 (optimally compressed) exabytes in 2007 (this is the information equivalent of 6 newspapers per person per day).[4] In the 1990s, the spread of the Internet caused a sudden leap in access to and ability to share information in businesses, at home and around the globe. Technology was developing so quickly that a computer costing $3,000.00 in 1997 would cost $2,000.00 two years later and only $1000.00 the following year.
