Are Reporters Necessary?

Interesting blog post here about the need for public relations professionals to video their clients when they're being interviewed by the press. That way if they're misquoted, or a spin is put on the story or the broadcast footage, you can counter with the actual, unedited footage, or the entire interview video or transcript on your client's social media outlet.

Which begs the question, then why is the reporter even necessary in the first place for getting a message out?
