How Much Information?

New information created is either stored in four physical media - print, film, magnetic and optical - and seen or heard in four electronic channels - telephone, tv, radio and internet. An interesting study (2003), by a team of researchers from the School of Information Management and Systems @Berkeley, attempts to estimate the amount of information created each year.

I like to mention this project because all the information sources/channels that I can possibly think of are included in this study!!
