Alexa
1996 April 1st
Brewster Kahle and Bruce Gilliat founded a company called Alexa Internet. The company’s original vision was to develop advanced web navigation that would continually improve itself on the basis of user-generated data. For this purpose, the Alexa toolbar 1.0 was created in 1997 as an extension of the browser. In 1999, Alexa Internet was bought by Amazon.
