7. “How Much Information? 2003” was a famous study at the School of Information and Management Systems at the University of Berkeley.
Professor Hal Varian of the University of Berkeley and his colleagues set out to answer the enormous question “How much new information is created each year.” This team of researchers estimates that the world’s total yearly production of information in the four physical media of print, film, magnetic and optical content would require roughly 1.5 billion GB of storage, the equivalent of 250 MB per human. Where possible, they have also compared their findings to their similar study done in 2000, to find out how much the amount of information had increased:
