It's not often you get to write the words such-and-such a broadcast "was the most watched ever," and I'm not going to let this historic opportunity pass either: "Super Bowl XLV" - the one pretty much all of us watched last night - was the most viewed telecast in TV history.
There you have it. The official count.
