It has been officially announced that Chillingo, the UK-based publisher of such immensely popular titles as Angry Birds and Cut the Rope has been acquired by Electronic Arts for an undisclosed sum of money, rumored to be $20 million in cash.

“By acquiring Chillingo, EA Mobile is increasing its market leadership on the Apple Platform as well as reaffirming its position as the world’s leading wireless entertainment publisher,” EA said in a statement. “This acquisition will combine Chillingo’s expertise in cultivating the ideas of independent developers with EA’s global mobile publishing reach.”

This news comes just over a week after ngmoco was acquired in a deal worth as much as $400 million. So it looks like its open season on successful iPhone publishers. Having just been recently announced, there has been no word on exactly what operational effect the EA deal will have on Chillingo’s day to day operations and whether it will be rolled into the EA Mobile brand or continue to be run as a separate entity.

The team would like to congratulate both EA and Chillingo on this huge deal and hope we continue to see the same fantastic and innovative titles coming out of the “new” Chillingo in whatever form it takes.
