Microsoft was pushing its Live Search service, including its cashback program, in June, propelling the company to the top of the list of most active online advertisers, according to comScore.
Microsoft ads were viewed 5.5 billion times by 126.4 million unique visitors, comScore reported. That’s 1.7 percent of all the online display ads served in the U.S. for the month and a reach of nearly 70 percent of the total unique audience.
Other top online advertisers were: University of Phoenix, Experian Interactive, United Online, Verizon, AT&T, Deutsche Telekom (I’m guessing that’s actually T-Mobile because this is a list of top U.S. online advertisers), Vonage, Netflix and the Ask Network.
On the publisher side, Fox Interactive Media lead by a healthy margin, serving 52.3 billion ad views in June for a 15.9 percent share. The vast majority of that was on FIM’s MySpace.com.
Yahoo served fewer ads — 34.7 billion for a 10.5 percent share — but reached an audience of 130.7 million unique visitors, substantially more than Fox’s 83.7 million.
Microsoft trailed Fox, Yahoo and AOL. The company’s sites served 15.5 billion ad views for 4.7 percent of the market. Ads on Microsoft sites reached 87.7 million unique visitors.
