I tried to look up some numbers since vice unfortunately didn't post any sources. The number of films released seems to be roughly correct (at least relative to each other), but Wikipedia says Nollywood's annual revenue is 10 billion USD, not 590 million USD. I will unpublish this snap later if I can't find any other sources.
I would leave it up, lets just try and get the stats right though as these don't add up, and if they did... I'm going to nollywood to start a production studio :)
