This article below had me enthused.

It was easier and cheaper to develop for two rather than 3, that and he probably only said that on the hopes BB 10 took off like a warpdrive.

Skype happened. ooVoo was probably backup in case Skype wouldn't come on the platform. Once BB got skype, they probably didn't bother with ooVoo anymore....
