Where can I find the search engine traffic numbers for the past 10-15 years?

Question

I'm doing a report and I need to find out how many searches, o were preformed on major search engines (yahoo, google, ask jeevs, msn, aol, etc) in the past 10-15 years or how many users these search engines had so I can gauge their growth, does anyone know where I can find this information

Answer 1

The Search Engine Marketing Association produces a report calledThe SEMPO Annual State of Search Survey 2007 which contains data on search engine traffic numbers though I doubt they go as far as that

Otherwise check with Nielsen/Netrankings for their historical data. They produce search engine share numbers including number of users on a monthly basis
