Origins/history of cocos2d-x

I am curious about the origins of cocos2d-x. I know it was a port of the Objective-C cocos2d, which was itself a port of the original Python cocos2d.

Was cocos2d-x originally developed in-house by China Unicom for the (now defunct) WoPhone? This first birthday post seems to indicate they were the original sponsor: http://www.cocos2d-iphone.org/1st-birthday-of-cocos2d-x/

Great to see cocos2d-x expanding and doing so well. The Fall 2013 video was very inspiring!

they were, then Chukong-inc bought the whole team. The Author of Cocos2d(python) and Cocos2d-iPhone now also work at Chukong and Cocos2d-x
