Every show gets canceled eventually, and so this rumor will one day be true. But not today.

As of now, CBS has neither renewed nor canceled "Blue Bloods" for another season of family dinners, precinct politics and, in between, busting bad guys.

"Blue Bloods" is in the midst of its 13th season, so you had better ask a professional gambler whether that's a factor for or against its continuation. Is it more likely to be renewed because CBS has done so 12 times already and clearly loves it? Or is it more likely canceled because, as I said, all shows get the axe one day and this show's luck has to run out sometime?

CBS generally issues its renewal and cancellation notices in mid-April, so we'll know one way or another soon enough.

I'm not a gambler, but in this case I think the smart money is on another renewal. Long-running procedurals like "Blue Bloods" are a central part of CBS's brand. And while the show's ratings have been slipping a little, it's no more than can be expected — it still averages six million viewers per episode, which is more than a lot of buzzier shows get.

And it's doing that on Friday night, which is traditionally a TV dead zone. Thanks in part to dependable old "Blue Bloods," CBS has owned Friday nights for a while.

It's worth noting that the show has beaten the rumor mill in the past. "Insiders" have said more than once that the show was about to get the chop, but it's still here.
