In a post on the Official Google Blog, Google announced that they were withdrawing from the search advertising partnership with Yahoo that was originally announced in June. In a press release the U.S. Justice Department stated that Google withdraw “after the Department of Justice informed the companies that it would file an antitrust lawsuit to block the implementation of the agreement”. The Justice Department said that the agreement “would likely harm competition in the markets for Internet search advertising and Internet search syndication” due to the companies accounting for over 90 percent of both markets. In Google’s post they stated they withdrew because of the risk of a protracted legal battle as well as “damage to relationships with valued partners.”
