Google launched its AdSense program, at first (before other things happened) it was named content targeting advertising in March 2003. The AdSense name was initially used by Applied Semantics, a competitive offering to AdSense. The name was adopted by Google after Google bought Applied Semantics in April 2003. Applied Semantics was started in 1998 by Gilad Elbaz and Adam Weissman.
Some advertisers complained that AdSense produced worse results than AdWords, since it served ads that related to the content on a web page and that content was less likely to be related to a user's commercial desires than search results. For example, someone (looking at web sites on) a (shared online writing page) dedicated to flowers was less likely to be interested in ordering flowers than someone searching for terms related to flowers. As a result, in 2004 Google allowed its advertisers to opt out of the AdSense network.
Paul Buchheit, the person who started the company of Gmail, had the idea to run ads within Google's e-mail service. But he and others say it was Susan Wojcicki, with the support of Sergey Brin, who organized the team that took the idea and changed for improvement into a hugely successful product. By early 2005 AdSense accounted for a guessed 15 percent of Google's total revenues.
In 2009, Google AdSense announced that it would now be offering new features, including the ability to "enable many networks to display ads".
In February 2010, Google AdSense started using search history in contextual matching to offer more relevant ads.
On January 21, 2014, Google AdSense launched Direct Campaigns, a tool where publishers may directly sell ads. This feature was retired on February 10, 2015.
Today, Google earns about US $4 billion ($13.6 billion annualized), or 22% of total revenue, through Google AdSense.
