ER might not end when you think it will end

No, NBC isn't thinking about giving the show another season, but they are definitely thinking about making this current last season of the show last just a little bit longer.

How are they going to do that? The network is planning to have the last 4 episodes of the show be 5 hours long each.

OK, I'm just kidding about that. Actually, they're thinking about increasing the number of episodes of this final season of ER from 19 to 22. A full season for many shows is usually around 22 episodes, so this wouldn't be anything special, but they did plan to have a shorter season of the show all along so this 3 episode increase is good news for fans. And probably the network too, since it still gets good ratings each week, even though it's been on the air since 1994.

The same thing happened last season. Everyone thought that the ratings would go down and that it would be the last season, and then the show started to do great in the ratings, even beating other NBC shows they tried.
