Not sure what Youtube and Netflix have to do with anything? Ditto WoW (really?) or Overwatch. VR maybe, though I think it's very niche culturally speaking and will die down very quickly once the initial buzz subsides and people have their fill of the tech and lacklustre launch games.
The truth is Nintendo have been basically on lockdown for two years and have had nothing to excite the world with, until NX is revealed hopefully. Then of course there are big occasional hits like Pokemon Go, the Super Mario Run reveal (the release could be huge), the Prime Minster of Japan dressing up as Mario for the 2020 Olympics, Zelda stealing the show at E3 + the insane queues for that, not to mention their plans to release animated films, the Universal Studios theme park etc...
They're very fortunate to have IP that anyone in the world would recognise, and that's a very strong position to be in.
