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

[JEMC]

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.

 

Edit: I see that mysteryman posted another reaction video of that woman. So I guess that besides being a trend, it's also a way for some people to get the attention they are looking for.
