Watching vlogs and YouTube videos of creators in a language you’re trying to learn can be one of the most fun, yet beneficial, ways to learn! There are even YouTubers who create videos for audiences just like you. Here is a great video showing just that!
I never considered watching YouTube videos in the language I’m learning, but now I think it could be the most beneficial way for me! I think it would actually be more effective than watching shows and movies 
I used to do this when I was studying French. It’s a great technique although it can be frustrating when you don’t understand what they are saying 
also the subtitles on Youtube are very slow
That’s how i learned english! Watching YouTube, tv series, movies, all are a great way to learn the language😄
