comScore’s Ad Focus ranking indicates that the AOL Advertising network was the online property with the greatest advertising reach in October 2009, reaching 91 percent of Internet users. Yahoo’s ad network followed, reaching 88 percent of the Internet population, whilst the Google Ad Network came in third with an 87-percent reach.

The October 2009 comScore Ad Focus ranking was, unsurprisingly, dominated by ad networks. Leading online brands such as Yahoo and Google, however, managed to come in 7th and 9th respectively in terms of their ad reach, while Microsoft’s Bing search engine cracked the 50th spot with a 33.1 percent reach.
