Comcast Corp (CMCSA.O), the owner of NBCUniversal, said on Thursday it would buy DreamWorks Animation SKG Inc (DWA.O) for US$3.8 billion.

The $41-per-share cash offer represents a premium of about 27 per cent to DreamWorks' Wednesday close.

Trading in Dreamworks shares, which have gained nearly 50 per cent in the last six months, was halted.

DreamWorks Chief Executive Jeffrey Katzenberg will become chairman of DreamWorks New Media, which will include the company's ownership interests in Awesomeness TV and NOVA.

Katzenberg will also serve as a consultant to NBCUniversal.

DreamWorks Animation, known for movie franchises such as "Shrek" and "Kung Fu Panda," was spun off from DreamWorks Studios in 2004. The studio was founded in 1994 by Steven Spielberg, David Geffen and Jeffrey Katzenberg.

The Wall Street Journal first reported on Wednesday that Comcast was in talks to buy DreamWorks Animation for over $3 billion.
