NBC has greenlit its first comedy for the 2012-13 season just as buzz began building for many more pilots vying for spots on primetime skeds across all the broadcast nets.

Thirteen episodes were ordered Friday of single-camera half-hour “Go On,” which stars Matthew Perry (“Friends”) as a sarcastic sportscaster trying to recover from a personal loss with the help of group therapy. From Universal Television, “Go On” has Scott Silveri (“Friends”) attached to write and executive produce with Karey Burke and Todd Holland of Dark Toy Entertainment.

“Go” also stars Julie White, Suzy Nakamura, Laura Benanti, Allison Miller and Khary Payton.

Dark Toy recently reupped with Universal TV. Shingle still has another comedy pilot under consideration, “Isabel.”

With development season kicking into high gear, NBC has started stocking up for the fall. Most recent orders have come on the unscripted side, including “Stars Earn Stripes,” “Howie Mandel’s White Elephant” and “Ready for Love.”

The network also is looking for at least one series to launch in August coming out of the Olympics.

A handful of other shows began generating buzz from test screenings and rough cuts that trickled into the Big 4 last week. Sources cautioned that chatter is hardly definitive and a significant number of pilots have still not been delivered to the nets.

Also looking good for pickup at NBC are half-hours “1600 Penn,” a comedy set in the White House, and “Friday Night Dinner” from Greg Daniels.

At ABC, a quartet of comedies are stirring early pickup talk: Sarah Chalke starrer “How to Live With Your Parents for the Rest of Your Life.”; Judy Greer starrer “American Judy”; “Malibu Country” starring Reba McEntire and Lily Tomlin (it’s seen as a potential companion for Tim Allen’s “Last Man Standing”) and “White Van Man,” starring Kyle Bornheimer.

Serial killer drama “Mastermind,” starring Kevin Bacon, as well as comedy “Rebounding,” are early frontrunners at Fox.

At CBS, drama “Ralph Lamb” is said to be well on its way to assembling a writing staff based on the strong feedback for the early 1960s-set Vegas drama starring Dennis Quaid, Michael Chiklis and Jason O’Mara.

Another Eye drama with heat is “Elementary,” the Sherlock Holmes vehicle starring Jonny Lee Miller and Lucy Liu.

Over at CW, the two most high-profile properties are considered locks for orders: “Arrow” and “The Carrie Diaries.” Insiders are raving about the perf of “Arrow” star Stephen Amell.

Also generating superlatives is Mamie Gumer, who stars as a medical intern in “First Cut.”

Fantasy dramas “Cult” and “The Selection” are seen as strong contenders, with “Selection” seen as being in the vein of “Hunger Games” in revolving around a poor woman chosen by lottery to enter a competish to become the new queen of a war-torn nation.

“Shelter,” from “One Tree Hill’s” Mark Schwahn and J.J. Abrams, lensed later than other CW pilots so it’s hard to get a read on it yet. And it’s no secret that CW’s “Beauty and the Beast” redo has been championed by prexy Mark Pedowitz, though it’s unclear yet how the finished product has been received.
