Dunno if you've seen this story.
Seems Microsoft have been paying YouTube gaming "personalities" to promote Xbox1 & its games.
Basically, Microsoft have said to these people, "We'll give you some cash if you only say positive or neutral things in your gameplay / Let's Play vids. Saying anything negative is a no-no if you want to get paid !"
Crucially, these "YouTubers" are not allowed to tell their trusting viewers about this arrangement.
I'm sure this sort of dodgy practice goes on all the time, but this time they got caught & it's being widely reported on.
I probably haven't explained this very well (knackered - been a long day) so here are some useful links :
