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 "On February 12, 2013, Comcast announced an intention to acquire the remaining 49% of General Electric's interest in NBCUniversal, which Comcast completed on March 19, 2013.". Is that enough to answer the question?
Answer: no
