I want to know the answer to the following question:
In 1947, what company did Universal buy a stake in?
All the background I'm provided with is that "Broadening its scope further, Universal-International branched out into the lucrative non-theatrical field, buying a majority stake in home-movie dealer Castle Films in 1947, and taking the company over entirely in 1951.". Is that enough to answer the question?
Answer: yes
