Each season, the television networks introduce dozens of new TV shows and hope that each will be a big hit in the ratings. Unfortunately, most are cancelled after one season. How are the 2017-18 series doing? Which have the best ratings and which have the worst? How many will survive to see a second season? Stay tuned.

Here are the season average ratings of the new 2017-18 network TV shows — through the end of week 21 (Sunday, February 10, 2018).

New ABC TV shows (so far): Child Support, The Good Doctor, Kevin (Probably) Saves the World, Marvel’s Inhumans, The Mayor, and Ten Days in the Valley.

New CBS TV shows this season (so far): 9JKL, Big Brother: Celebrity Edition, Me Myself & I, SEAL Team, SWAT, Wisdom of the Crowd, and Young Sheldon.

Note: Though Will & Grace isn’t technically a new show, we’re treating it as such because it’s been off the air for 11 years.

The averages are based on the final national numbers (live plus same day viewing). The demos are typically reported with one decimal place but I’ve included two for more accurate ranking.

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.

What do you think? Are you surprised by any of the ratings? Which shows should be doing better?
