NBC 2014-15 Season Ratings (updated 9/21/15)

After struggling for years in the ratings, it seems that NBC is really starting to turn things around. Of course, they still have their challenges. Which NBC TV shows will be cancelled and which will be renewed? Stay tuned!

There’s lots of data that NBC looks at when deciding whether to renew or cancel a TV series but the ratings are typically the biggest piece. Here’s how the network’s shows are doing.

NOTE: The 2014-15 season concluded on September 20, 2015. You can see the NBC ratings for the 2015-16 season here.

A couple of notes about these charts:
These figures are updated automatically as new ratings are released. The averages are based on the final national numbers (live plus same day viewing), unless marked with an asterisk (*). For technical reasons, I have to resort them manually so feel free to let me know if I missed something.

Keep in mind that the demo numbers are typically what’s most important to advertisers. Therefore, that’s how the networks measure success. Advertisers pay more for ad time on a show that has a higher demo rating. Because older viewers don’t count? No, it’s because younger viewers watch less traditional TV and are harder to reach.

Demo numbers are typically reported using the 10ths decimal place (2.4, for example). In the averages, I’m using an extra decimal for easier ranking. The networks take into account when shows air on Fridays and Saturdays, nights when TV viewership is lower.

What do you think? Which shows are you rooting for? Which one isn’t as big a hit as you thought? Are you hoping any series will get cancelled to make way for something else?
