You haven't had many options for streaming video on the Switch. There's Niconico in Japan, Hulu... and, well, that's about it. Another option might be right around the bend, however. In the wake of hints from this spring, people searching Nintendo's website for games have received suggestions for a Switch-native YouTube app that would be available November 8th. You can't currently visit a product page for it, but the listing by itself speaks volumes.
