Only 11 of the first 46 Super Bowls have drawn a television rating of at least 46, so how will you be betting on the Super Bowl XLVII prop on TV ratings?
Online sportsbook is listing an OVER/UNDER of 46 on the national American television rating for Sunday's Super Bowl.
Bovada has also posted an O/U on the average viewership of 111 million.
And finally, they feel the Baltimore TV viewing rating will be stronger than San Francisco's. It was sitting at -150 in the market-vs.-market match-up, with the 49ers' home town getting +110.
