Electronic Arts has announced that they have signed a five-year agreement with Facebook. The two companies say that the strategic relationship will simplify the experience for users by making Facebook Credits the sole payment method of EA games on Facebook; they will receive 70 percent of revenue as is standard for Facebook Credits.

Since gaming has emerged as the most popular category of applications on Facebook, the natural next step is for EA to broaden its relationship with Facebook and its 500 million users, said Barry Cottle, Senior Vice President and General Manager for EA Interactive. Our goal is to make the best games tailored specifically to the platforms on which people want to play.

EA recently launched Monopoly for Facebook, and is bringing Pogo Games to Faceboook. The Pogo program is currently in beta and already includes Poppit!, Word Whomp, Scrabble and Boggle.

We are pleased to enter into this long-term partnership with EA to make it easier for people to purchase virtual goods across some of the most popular games on Facebook, said Dan Rose, vice president of partnerships and platform marketing at Facebook. Playfish has a great reputation for building high-quality games on Facebook, and we look forward to working even more closely with them and the larger team at EA.
