What are some of the pros of mainstream media

People could get paid such as printing or writing newspapers.

Some of main advantages of mainstream media would for example be that it has a global scope (point of view from over the world), it is also taken as being more professional information compared to what would be a blog post for example. News Reporters for example have to research to make sure that what they're stating has some validity and they are also supervised to make sure it is thorough and accurate. Hope this helps! :)
