EDITORS, PLEASE NOTE:

HBO has confirmed that the new seasons of THE NEWSROOM, THE COMEBACK and GETTING ON will debut back-to-back on SUNDAY, NOV. 9, starting at 9:00 p.m. (ET/PT).

THE NEWSROOM begins its six-episode, third and final season, SUNDAY, NOV. 9 (9:00-10:00 p.m.). Created by showrunner Aaron Sorkin, the drama series follows the members of a cable news team on their quixotic mission to do the news well in the face of a fickle audience, corporate mandates and tangled personal relationships. Sorkin, Scott Rudin and Alan Poul return as executive producers, with Paul Lieberstein joining the show as an executive producer. Returning cast regulars include Jeff Daniels, Emily Mortimer, Sam Waterston, John Gallagher, Jr., Alison Pill, Thomas Sadoski, Dev Patel and Olivia Munn.

THE COMEBACK returns for its eight-episode season SUNDAY, NOV. 9 (10:00-10:30 p.m.). The limited comedy series stars Lisa Kudrow as the embattled Valerie Cherish, a fading TV "It Girl" who was once so desperate to stay in the spotlight that she allowed cameras to follow her every move as she appeared on a new sitcom - with disastrous results. Now, it's ten years later, and Valerie thinks she has it all figured out this time. She doesn't. Created by Michael Patrick King and Lisa Kudrow, who serve as executive producers along with Dan Bucatinsky.

GETTING ON launches its six-episode second season SUNDAY, NOV. 9 (10:30-11:00 p.m.). From creators Mark V. Olsen and Will Scheffer, the series follows the daily lives of nurses and doctors as they struggle with the darkly comic realities of caring for the elderly in an overwhelmed healthcare system, skewering the petty bureaucracies of modern medical practice in America. Laurie Metcalf, Alex Borstein, Niecy Nash and Mel Rodriguez star.
