I want to know the answer to the following question:
What movie studios did Comcast and their partner buy?
All the background I'm provided with is that "On April 8, 2005, a partnership led by Comcast and Sony Pictures Entertainment finalized a deal to acquire MGM and its affiliate studio, United Artists, and create an additional outlet to carry MGM/UA's material for cable and Internet distribution.". Is that enough to answer the question?
