In 1995, Microsoft was selling a CD-Rom based encyclopedia, Encarta. The same year another encyclopedia project was begun online, Wikipedia. Over the 15 years that followed,
Encarta grew into the most respected and cited encyclopedia because it had the backing of one of the largest corporations in the world.
Wikipedia became the most comprehensive and popular encyclopedia ever produced by providing an interactive platform where anyone could contribute their own knowledge and thus others could gain insight and knowledge.
Encarta dominated the market because of Microsoft's inventive use of computational tools to create new and original content.
Wikipedia's dominance over Encarta has been the result of using web crawler algorithms to collect and process information, creating insight and knowledge for its users.
