It really should.
I think the closest that comes to actually knowing what's probably being watched across all media in aggregate, would be TorrentFreak's Top 10 Most Pirated Movies of The Week list[1].
But even that is really not completely accurate because not everybody that pirates necessarily consume what they pirate. Some just hoard for hoarding's sake.
Honestly I'd rather have the inverse - Top 10 least watched TV and films. I don't want to see what everybody else has already seen. I want to find the less watched rare stuff, quicker.
