Native speakers! Please help me..."from" or" through television"?

Dear all,

I'm currently writing a paper in Linguistics on language learning from/through television. But I'm not sure about the preposition. The paper is about whether or not it is possible to improve one's foreign language skills through (?) watching television and the title is going to be either "Language learning from television" or "Language Learning through television". What would native speaker's say? Could you please tell me which preposition is correct or which one sounds better?

Thank you very much for your help!
