companies don't pre-tease Superbowl commercials, do they?

They do this year! I've seen a few tease videos on Tumblr because one of the upcoming Superbowl ads (apparently) features one of the main Stranger Things actors and I'm following a Tumblr focused on him. So yeah, teaser commercials for commercials are now a thing. >_>

(Edit: That's a neat ad, though! I don't play - beyond catching a few just for fun - but that's really magical. :D)
