This is from an article about the Google press release when they bought A.S.: " Google said that Applied Semantics' products and engineering team will strengthen Google's search and advertising programs, including its "fast-growing content-targeted advertising offering"" . At the time, Applied Semantics had a license deal with Overture, which was also doing content-targeted advertising and AS software was used to enable it." My guess is whatever Google had in place was significantly enhanced by the A.S. software.
