The Superbowl had the highest viewership of anything since the Moon Landing, you don’t get those numbers without universal appeal.
Um, that probably had to do something with the current girlfriend of a certain player.
Yes - that didn’t hurt but it was a GREAT matchup. An absolutely loaded team against a team trying to become the first repeat champ since the (first) dynastic Patriots run. And a QB trying to become the GOATNNTB (Greatest of All Time Not Named Tom Brady) and I think the game being in Vegas added to its appeal as well…. music was a letdown though
