The term "social media" is meaningless at this point. People call all kinds of online services social media. In practise it typically refers to Facebook, Instagram, Twitter and YouTube. And I have a really hard time seeing what is "social" about YouTube, because of the huge asymmetry between creators and watchers. Even when you have reaction videos between different content creators, there is nothing social going on.
