I want to know the answer to the following question:
On what date was Comcast's purchase of controlling interest in NBCUniversal reported?
All the background I'm provided with is that "Following a tentative agreement on by December 1, on December 3, 2009, the parties announced that Comcast would buy a controlling 51% stake in NBCUniversal for $6.5 billion in cash and $7.3 billion in programming.". Is that enough to answer the question?
Answer: yes
