More than 26 percent growth to about $10 billion (7.09 billion EUR) was achieved by U.S. Internet advertising revenues in the first six months of the year.
Keyword ads - such as those displayed alongside search results at Google Inc. and other search engines - remain the most lucrative, accounting for about 40 percent of online revenues.
Display ads made up 21 percent of total revenue and classifieds had 17 percent. Other formats include video, e-mail and sponsorship ads.
