The Growth of Information in Society

The growth of technologically mediated information has been quantified in different ways, including society's technological capacity to store information, to communicate information, and to compute information. It is estimated that the world's technological capacity to store information grew from 2.6 (optimally compressed) exabytes in 1986, which is the informational equivalent to less than one 730-MB CD-ROM per person in 1986 (539 MB per person), to 295 (optimally compressed) exabytes in 2007. This is the informational equivalent of 60 CD-ROM per person in 2007 and represents a sustained annual growth rate of some 25%. The world’s combined technological capacity to receive information through one-way broadcast networks was the informational equivalent of 174 newspapers per person per day in 2007. The world's combined 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, which is the informational equivalent of 6 newspapers per person per day in 2007. The world's technological capacity to compute information with humanly guided general-purpose computers grew from 3.0 × 10^8 MIPS in 1986, to 6.4 x 10^12 MIPS in 2007, experiencing the fastest growth rate of over 60% per year during the last two decades.

James Beniger describes the necessity of information in modern society in the following way: “The need for sharply increased control that resulted from the industrialization of material processes through application of inanimate sources of energy probably accounts for the rapid development of automatic feedback technology in the early industrial period (1740-1830)” (p.174) “Even with enhanced feedback control, industry could not have developed without the enhanced means to process matter and energy, not only as inputs of the raw materials of production but also as outputs distributed to final consumption.”(p.175)
