It’s hard to believe that 60 Minutes is in its 45th season. How long will the TV series continue? Probably as long as the ratings make it worthwhile for the network.

60 Minutes airs on Sunday nights on CBS. Correspondents include Steve Kroft, Lesley Stahl, Bob Simon, Scott Pelley, Morley Safer, Byron Pitts, Lara Logan, Anderson Cooper, and Dr. Sanjay Gupta.

Below are the TV show’s ratings for the 2012-13 season, the best way to tell if 60 Minutes will be renewed for a 46th year (though it’s hard to imagine that the series will ever be cancelled).

These figures will be updated as the weeks progress so be sure to bookmark and return to this page:
