Is "Law & Order" on the way out?

Maybe. It seems, once again, the long-time NBC show is on the bubble -- that insecure spot where its unclear whether the ratings (or advertising dollars) warrant the show's return for another season.

(Although with reruns of the various L&Os on Bravo, TNT, USA and network TV we'll always have Jack, Lu, Lenny and the gang.)

And what of "Chuck" and "Medium"? Or the CW's last comedies "The Game" and "Everybody Hates Chris"?

This Variety piece explores what's bubble-licious and how showrunners deal with the uncertainty. Read it and find out whether you need to get those 'save my show' campaign ideas rolling.
