Social networking website Facebook, backed by software giant Microsoft is expected to reveal a new system in online advertising this afternoon. The system will veer from the normal online advertising - geared toward a general mass audience - to a more personalized way of targeting potential customers.

Using information from Facebook's 50 million member profiles, the new advertising system can interpret the user data to gear specific advertising toward them. For example, a member of the social network claiming to be a Detroit Pistons fan may see increased marketing from NBA or NFL pro shops. Or, as the Presidential election inches closer, members registered as Democrats may see more ads soliciting campaign contributions. The new honing of online ads is sure to drive increased revenue to the site, as advertisers can now be sure their marketing strategies are concentrated in all the right places.

Currently, shares of Microsoft - a huge benefactor of the website - are trading at $36.35, down 0.47%.
