Facebook and PayPal today announced a relationship to offer PayPal in key parts of Facebook's advertising and developer systems. As part of the relationship, advertisers around the world will soon be able to use PayPal to pay for Facebook Ads through the company's online advertising tool. For businesses in areas where the payment process can be difficult and expensive, the option to pay with PayPal makes it even easier for advertisers, particularly small international companies, to run campaigns on Facebook. Facebook reaches more than 400 million people, 70 percent of whom live outside the United States.

In addition, PayPal will become a payment option for Facebook Credits, which is currently being tested in a small number of games and applications. The goal of Facebook Credits is to give users a fast and easy way to buy virtual goods on Facebook, including items from the Facebook Gift Shop.
