AdSense~History

The underlying technology behind AdSense was derived originally from WordNet and Simpli, a company started by the founder of Wordnet — George A. Miller — and a number of professors and graduate students from Brown University, including James A. Anderson, Jeff Stibel and Steve Reiss. A variation of this technology utilizing Wordnet was developed by Oingo, a small search engine company based in Santa Monica founded in 1998. Oingo focused on semantic searches rather than brute force string searches. Oingo changed its name to Applied Semantics, which was then bought by Google for $102 million in April 2003, to replace a similar system being developed in house.
