<!-- What but does Oingo/Semantics have to do with AdSense, especially since it was bought after AdSense was launched? -->

Google launched its AdSense program, originally named "Content targeting advertising" in March 2003.<ref>{{cite web|last=Matt |first=Cutts |title=Google Guy |url=http://www.webmasterworld.com/forum81/376.htm |publisher=Web Master World |url-status=dead |archive-url=https://web.archive.org/web/20140304190508/http://www.webmasterworld.com/forum81/376.htm |archive-date=2014-03-04 }}</ref> The AdSense name was originally used by Applied Semantics, a competitive offering to AdSense. The name was adopted by Google after Google acquired Applied Semantics in April 2003.<ref>{{cite web |url= http://googlepress.blogspot.co.uk/2004/04/google-acquires-applied-semantics.html |title=Google Acquires Applied Semantics |work=News from Google |date=April 23, 2003 |access-date=July 12, 2014}}</ref> Some advertisers complained that AdSense yielded worse results than [[Google Ads]], since it served ads that related contextually 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 browsing a blog 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.<ref name=Battelle>{{cite book|last=Battelle|first=John|title=The Search|year=2005|publisher=Penguin|location=New York|isbn=978-1-85788-361-9|pages=151–2}}</ref>

[[Paul Buchheit]], the founder 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 backing of [[Sergey Brin]], who organized the team that adapted that idea into an enormously successful product.<ref>{{cite web |url= http://www.mercurynews.com/ci_17286427 |title=Susan Wojcicki: The most important Googler you've never heard of |first=Mike |last=Swift |work=[[San Jose Mercury News]] |date=February 7, 2011 |access-date=July 12, 2014}}</ref> By early 2005 AdSense accounted for an estimated 15 percent of Google's total revenues.<ref name=Battelle /> In 2009, Google AdSense announced that it would now be offering new features, including the ability to "enable multiple networks to display ads". In February 2010, Google AdSense started using search history in contextual matching to offer more relevant ads.<ref>{{cite news |first=Julianne |last=Pepitone |title=Google expands ad targeting methods |url=https://money.cnn.com/2010/02/12/technology/google_adsense/index.htm |work=[[CNNMoney.com]] |date=2011-02-12 |access-date=2012-07-26}}</ref> 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.
