The five broadcast networks (ABC, CBS, Fox, NBC and the CW) made more than 80 pilots this year. Last week, as the networks gave some potential series the OK to begin assembling their staffs, word leaked out that some shows had been given the good news early. But many decisions were made over the weekend, with the Hollywood trade papers and websites reporting breathlessly that certain pilots' fortunes had risen, while others had peaked too soon or proved disappointing.

By today, at least NBC and Fox will have made their decisions. Here's a look at what to expect at today's announcements.

NBC

The new season of "30 Rock" — its seventh and final season — will be abbreviated, with only 13 episodes. "Parenthood" was picked up for a fourth season. NBC also renewed long-running drama "Law & Order: SVU" and is getting even cozier with Dick Wolf, picking up his pilot "Chicago Fire" for the 2012-13 season. The show centers on the men and women of the Chicago Fire Department. The series stars Taylor Kinney ("The Vampire Diaries") and Jesse Spencer ("House").

Among NBC's new shows, "Do No Harm" is a medical drama that puts a twist on the classic Dr. Jekyll and Mr. Hyde story. "Infamous" features a detective who goes undercover to the rich family she grew up in — as the maid's daughter — to solve the murder of the heiress who had been her best friend.

NBC is adding more comedy to its roster with "1600 Penn" and "Animal Practice."

"1600 Penn" is a White House family comedy, with Bill Pullman as president. The series, which comes from "Modern Family" director Jason Winer, former speechwriter to President Barack Obama Jon Lovett and "Book of Mormon's" Josh Gad (who will also co-star in it), has received a 13-episode order.

Also getting a 13-episode order is "Animal Practice." The series centers on a veterinarian, played by Justin Kirk ("Weeds"), who loves animals but loathes their owners.

These shows join the Matthew Perry-helmed "Go On," "Save Me" with Anne Heche," the J.J. Abrams-produced drama "Revolution" and Ryan Murphy's "The New Normal."

Fox

The network renewed its Kiefer Sutherland-led drama "Touch" and canned "Alcatraz" and "Bones" spinoff "The Finder."

The network may be losing a grumpy doc with "House" ending its run this season, but its staying in the medical practice with "Mob Doctor."

"My Boys" alum Jordana Spiro stars as a thoracic surgeon who becomes indebted to the South Chicago Mafia and is forced to moonlight as a "mob doctor."

Fox has also given a series order to the "The Following" from "The Vampire Diaries' " Kevin Williamson. It features Kevin Bacon as a former FBI agent searching for a serial killer.

Meanwhile, Fox is adding some comedies. "Ben & Kate" centers on a single mother whose brother moves in to help raise her baby.

"Goodwin Games," from "How I Met Your Mother" scribes Carter Bays, Craig Thomas and Chris Harris, follows siblings who inherit their late father's fortune. The cast includes Becki Newton ("Ugly Betty") and Scott Foley ("Grey's Anatomy," "Felicity").

And "The Office's" Mindy Kaling makes the move to the top-rated network in "It's Messy," in which she plays a doctor trying to balance her personal and professional lives.

The project, which she is to write, executive produce and star in, will mark her departure from the NBC comedy.
