SAN FRANCISCO (AP) — Microsoft, Yahoo and AOL are teaming up to sell some of the online advertising space that they have had trouble selling on their own.
The alliance announced Tuesday represents a joint attack on Google. The Internet search leader has become an even more powerful force in Internet marketing since paying $3.2 billion to acquire the DoubleClick advertising service in 2008.
Meanwhile, Microsoft Corp., Yahoo Inc., and AOL Inc. have been struggling to keep pace.
Microsoft has been losing billions in its online division while revenue has been sliding at both Yahoo and AOL.
The partnership covers a category of advertising that doesn't typically appear in the prime slots on websites.
By working together, Microsoft, Yahoo, and AOL are betting they can save money and sell more advertising.
