There has been a surprising amount of ‘net chatter in the past week about a rumor claiming NBC told the writers of Heroes to prepare for the end of the show. I have no way of judging the truthfulness of that, and there may be some other (unknown to me) factor that could take the show off the air. However, looking at the ratings, while the show is way down from its earlier years, considering that its on NBC, Heroes is far from being dead. It’s average, and networks don’t typically cancel their average shows, particularly ones that air at 8pm.

I am a stubborn man, but I’d like to think not infinitely so. If the 3 CBS scripted shows can survive on Friday’s with their ratings, there’s a chance that Law & Order can too. This has nothing to do with the check from Dick Wolf that arrived yesterday.

The ratings carnage at NBC is so complete that unless a miracle happens this spring with their new shows (and their development slate) the network very well may have to have to hold its nose and keep some of its well below average performers. If that happens, 30 minute sitcoms like Community and Parks & Recreation are the likely candidates, not a drama like Mercy.

Trauma didn’t receive an order for its “back 9” episodes, so it’ll last at most 13 episodes and then be canceled. It may be pulled from the schedule sooner than that.

Although SNL: Weekend Update is a scripted show, since it was limited run, I’m not including it.

This is a breakdown of NBC scripted shows and their renewal and cancellation prospects. Here are links to the other networks:


The Renew/Cancel Index is a show’s Season To Date adults 18-49 rating divided by its network’s Season to Date average 18-49 rating. If a show’s season to date 18-49 ratings average equalled its network’s 18-49 average, the show would have an Index of 1.00. Without special factors, scripted shows that were more than 10% below their network’s average are typically canceled by the end of the broadcast primetime season.

Factors that could cause a show to be renewed with a well below average Index:

  • (F) -Fridays: Shows airing on Fridays have been renewed with significantly lower than average Indexes.
  • (S) – Syndication: Shows nearing syndication (66-88 episodes), often have economic factors that trump ratings leading to renewal.
  • (T) – Third Party: Shows that have a portion of their cost underwritten by a 3rd party can be renewed with substantially lower ratings.
  • (P) – Produced by the network’s production company – For shows on the bubble, being produced by the network’s corporate production company can be a survival advantage. For real losers, it’s unlikely to help.

While I initially tried to designate shows with “plum” timeslots, I think that’s hard to make that call at this point in the season. It’s likely still a factor, but will have to be an “after the fact” call.
