Some headlines called Sunday's Super Bowl the highest-rated ever. Not true, it did a fairly average number. It's just that the viewing universe has expanded (and maybe the counting method), so the total number of viewers is high. You could call it the "most-viewed Super Bowl," but as a Giants fan, I question that number, too.
NBC says: Super Bowl XLIII is now the most viewed television program in U.S. history with a total audience of 151.6 million viewers, according to official national ratings data released today by Nielsen Media Research. They're counting anyone who laid eyes on it, and I still think there were as many watching last year's.
At first officials said it was No. 2; then it was suddenly No. 1. Get used to such claims in the future. When all the journalists go away (as newspapers are in free-fall), there will no one left to check the claims made by power brokers and big companies.
