Global Capacity, Digitization, and Trends
In a recent study in Science it was estimated that the world's technological capacity to store information in analog and digital devices grew from less than 3 (optimally compressed) exabytes in 1986, to 295 (optimally compressed) exabytes in 2007, doubling roughly every 3 years.
In a less comprehensive study, the International Data Corporation estimated that the total amount of digital data was 281 exabytes in 2007, and had for the first time exceeded the amount of storage.
It is estimated that the year 2002 marked the beginning of the digital age for information storage, which means that this years marked the date where human kind started to store more information on digital, than on analog storage devices. In the year 1986, merely 1% of the world's capacity to store information was in digital format, which grew to 3% by 1993, 25% in the year 2000, and exploded to 97% of the world's storage capacity by 2007.

Famous quotes containing the words global and/or trends:
“The Sage of Toronto ... spent several decades marveling at the numerous freedoms created by a “global village” instantly and effortlessly accessible to all. Villages, unlike towns, have always been ruled by conformism, isolation, petty surveillance, boredom and repetitive malicious gossip about the same families. Which is a precise enough description of the global spectacle’s present vulgarity.”
—Guy Debord (b. 1931)
“Power-worship blurs political judgement because it leads, almost unavoidably, to the belief that present trends will continue. Whoever is winning at the moment will always seem to be invincible.”
—George Orwell (1903–1950)
