Description: "This study is an attempt to estimate how much new information is created each year.  Newly created information is distributed in four information flows: telephone, radio and TV, and the Internet.  This study of information storage and flow analyzes the year 2002 in order to estimate the annual size of the stock of new information contained in storage media, and heard or seen each year in information flows."

"Where reliable data was available we have compared the 2002 findings to those of our 2000 study (which used 1999 data) in order to identify trends - recognizing that 1999-2002 were years of relatively low economic activity."
