Where did this stupid "trend" come from? Game trailer reaction videos?

I believe this trend comes from people doing that with movie trailers. I mean, who hasn't seen the video of that woman reacting to the 50 shades of grey trailer?

Now it's the same with game trailers.

 

I hope this won't last long.
