Here are descriptions of the new drama series:

"Parenthood": From the executive producers of the box-office hit "Parenthood" -- Ron Howard and Brian Grazer, and writer/executive producer Jason Katims, the series is a contemporary re-imagining of the blockbuster film. The cast includes Peter Krause, Maura Tierney, Craig T. Nelson, Dax Shepard, Bonnie Bedelia, Monica Potter, Erika Christensen and Sarah Ramos as the colorful and imperfect Braverman family, now grown up and parents themselves.

"Trauma": This new medical drama is an intense, action-packed look at one of the most dangerous medical professions in the world: first responder paramedics set. The series, set in San Francisco, stars Derek Luke, Cliff Curtis, Anastasia Griffith, Aimee Garcia, Kevin Rankin and Jamey Sheridan.

"Mercy": The twist for this new medical drama is that it is seen through the eyes of the nurses on staff at Mercy Hospital. "Mercy" stars Michelle Trachtenberg, Taylor Schilling, Jamie Lee Kirchner, James Tupper, Diego Klattenhoff, and Guillermo Diaz.

"Day One": "Day One" tells the story of life on earth following a global catastrophe that has devastated the world's infrastructures. Beginning with the immediate aftermath of the cataclysmic event, an eclectic band of survivors -- played by Adam Campbell, Catherine Dent, Julie Gonzalo, David Lyons, Derek Mio, Carly Pope, Thekla Reuten and Addison Timlin -- strives to rebuild society as they unravel the mysteries of what happened and face their uncertain future.

Here are descriptions of the new drama series:

"100 Questions": This new comedy series' goal is to provide funny answers to 100 questions about love. Charlotte Payne (Sophie Winkleman) is looking for love and has rejected multiple marriage proposals -- but she has yet to meet Mr. Right. When she joins a popular online dating site, she gets a little help from her dating counselor Ravi (Amir Talai) -- who requires her to take a 100-question compatibility test. The questions aren't easy for Charlotte to answer, and each one requires her to recount a poignant and humorous time in her life with friends Leslie (Elizabeth Ho), Jill (Joy Suprano), Mike (Christopher Moynihan) and Wayne (David Walton).

"Community": From Emmy Award-winning directors Joe and Anthony Russo ("Arrested Development") comes "Community," a comedy series about higher education -- and lower expectations. The student body at Greendale Community College is made up of high-school losers, newly divorced housewives, and old people who want to keep their minds active. Within these not-so-hallowed halls, "Community" focuses on a band of misfits, at the center of which is a fast-talkin' lawyer whose degree has been revoked (Joel McHale), who form a study group and end up learning a lot more about themselves than they do about their course work. In addition to McHale, the series also stars: Gillian Jacobs, Yvette Nicole Brown, Danny Pudi, Alison Brie, and comedy legend Chevy Chase.
