Facebook has launched a new online advertising service that target users on any website using their Facebook details. Called Atlas, the service is designed to take on Google's lucrative AdWords service. It will allow Facebook to sell ads that 'follow' users across the web and mobile devices. Atlas  tracks people based on their Facebook log-in information Cookies are used to track browsing on desktop computers. Hoqwever, they don't work for mobile devices - a growing source of Internet traffic. Atlas solves that problem by tracking people based on their Facebook log-in information. Advertisers using the platform can then request that their ads be targeted to a specific subset of users - for example, young people in the suburbs using mobile devices.
