They just did a 10 billion dollar deal for Zee in India... What are you on about? You're obviously not familiar with Sony's strategy, but that doesn't mean they don't have one.
Sony is trying to expand globally in markets like India and increase the size of their reach. That's why you see Sony working with game studios in Korean and China.
Did you see them spending 10 billion on Zee or was that a surprise to you? Obviously, you didn't see it happening because you still were unaware that it was happening.
But you don't know about how Sony was able to afford Culver Max. They changed the name of Sony Pictures India to Culver Max which will be a merged entity between Sony Pictures India and Zee. Sony will own a little over 50% of Culver Max. Sony is throwing in cash into the new entity, but it appears to be an all-equity deal.
