Just a couple of interesting infographics showing time-line history of search engines. Without search engines, the internet would be practically useless in terms of getting to random information fast. Its all very well having all that information available at the click of a mouse, but if it were not for the ability to quickly search the vast amount of information available you could only really use the internet to reference specific things that you have at least enough knowledge to find further information about. Note it all properly started for the masses I guess around 1994, though the first infographic goes back further.
