Google are celebrating their 10th birthday, google have released their search engine to replicate searches in 2001 (yes i know that wasnt 10 yrs ago, its all they had going back so far)
its pretty interesting.http://www.google.com/search2001.html
"If you have 10 minutes to spare, take a look at an archive that Google has posted to mark the company's 10th anniversary. The search engine and its results are based on data from 2001, but it's interesting to see what turns up when popular 2008 terms are entered. For instance, iPod generates a reference to Image Proof of Deposit Document Processing System, and the 771 Barack Obama results centered around his duties as an Illinois State Senator."
