“Community” has killed “Made in Jersey.”

Or rather, the absence of “Community.”

One day after NBC announced it would stick with its current Friday lineup — “Grimm” repeat at 8 leading into “Grimm” originals at 9 — canceling plans to debut comedies “Community” and “Whitney” at 8 next week, CBS announced it had yanked it’s new Friday drama, “Made in Jersey” effectively immediately.

“CSI: NY” will move back into the 9 p.m. hour right away, and CBS will plug that 8 p.m. hour on Fridays with “NCIS” and “Hawaii Five-0” repeats — until the reality series “Undercover Boss” debuts there Nov. 2.

That makes “Made in Jersey” the season’s first cancellation, for dead-pool purposes.

Here’s what’s going on:

Before the season started, conventional wisdom had CBS winning this season among advertiser-preferred 18- to49-year-old viewers, beating out last season’s front-runner, Fox.

But lo and behold, two weeks into the season, the perennially “mired in fourth place” NBC is out front, with CBS close behind.

CBS has the edge in the preferred age bracket on Wednesdays, and Thursdays — and there’s nothing much CBS can do right now about NBC’s “The Voice”-fueled Monday lead in the age bracket, or its NFL-fueled Sunday lead. The two networks are duking it out on Tuesdays and Fridays.

Late Wednesday afternoon, NBC responded to CBS’s move, announcing that, on Oct. 30 -- the first Tuesday of the November sweep — it would pull “Parenthood” for that night only, and slide its two new comedies “Go On” and “The New Normal,” to 10 p.m., in order to inflate “The Voice” that night to a two-hour episode. (This week CBS surrendered its its two-week lead over NBC on the night among younger viewers.)

In case you missed its two episodes, “Made in Jersey” starred Brit Janet Montgomery as a working-class woman from Jersey practicing law at a hoity-toity New York law firm.
