According to wired[dot]com
Facebook's long-awaited Google
AdSense competitor is finally here. It's called Atlas, and it will
allow brands to use the social network's massive trove of data
to target ads on sites across the web. 1
Facebook announced the news late Sunday night to coincide with the start of Advertising Week in New York City. For other brands hoping to make headlines at Advertising Week,
Facebook's news will be a tough act to follow. Investors and the media have been waiting for an
announcement like this for years.

In January, Facebook took its first steps in this direction launching a network that could serve up
ads within mobile apps. But the launch of Atlas symbolizes a
deeper commitment to controlling the web's ads—and an even fiercer fight with Google for that control.
Atlas is not a new platform, perse.
Facebook acquired the
product from Microsoft last year.

But according to a blog post from Erik Johnson, head of Atlas, the team has rebuilt the platform
"from the ground up" in the hopes of making it easier for
advertisers to follow a consumer, regardless of what type of device
she's using.
In an apparent dig at Google, Johnson writes that the method advertisers have traditionally
used to track consumers— cookies—is flawed, because consumers are no longer using
one device at all times.

"Cookies
don't work on mobile, are becoming less accurate in demographic
targeting and can't
easily or accurately measure the customer purchase funnel across browsers and devices or into the
offline world," Johnson writes
