I’m building an educational video on demand platform which will leverage movies and tv shows as content. Does anyone know how and where to get licenses for them? I know there are business models where companies are allowed to use movies for 45-50% of startup’s income. is it really achievable and how difficult it is?
Each content owner either has their own licensing department or works through a licensing bureau. There's no standard. You will likely need to negotiate individually with every single content owner, even if managed by a bureau.
As for whether this leads to an economically viable business opportunity, you need to do direct research and validate your marketing strategy to determine if it's a business worth pursuing, based on your goals and available resources.
This isn't even a fully formed idea yet. Keep working on it.
