EA bought 2 year old social networking games company Playfish for $300 million

"The US video game publisher Electronic Arts has paid $275m (£170m) in cash, plus $25m in share options, for two-year old gaming company Playfish.
The deal could cost a further $100m if Playfish hits certain financial targets by December 2011.
Playfish is different from many rivals as it makes free games for social networking sites - such as Facebook and MySpace - and mobile phones.
Players typically will then start paying for extras as they get hooked.
Playfish has 60 million registered users for its virtual games, such as Pet Society and Restaurant City."
