For the last 5 years, there is no other company that has changed the way we work and look for evidence like Google. To Know more about this 21st century corporation, read "The Google Story" of David Vise and Mark Malseed.
After Google Earth, the next exciting project these guys are up to is to digitize all books that exist on earth (or, for the beginning, a major part of them). This is what "Der Spiegel" writes in its English edition:
This library would represent the culmination of a democratization of knowledge that began with the invention of printing. The little Google search window would be the gateway to the content of the 32 million books, 750 million articles, 25 million songs, 500 million images, 500,000 films, 3 million television programs and 100 billion public Web pages that Wired writer Kevin Kelly estimates humanity has published since the days of Sumerian clay tablets. To store all of this gigantic volume of data -- estimated at 50 petabytes -- would still require a building the size of a small town's library, Kelly wrote in a 2006 article for the New York Times. But in the future, all of that knowledge will be only a mouse click away -- and will fit on a single iPod.
