The West Wing creator insisted that the fictional newsroom in which the show takes place is not meant to be based on any real one, The Hollywood Reporter states.
"It takes place in a fictional newsroom, I want to stress that," Sorkin said. "It's not meant to be MSNBC or Fox or CNN."
"But it is cable news, covering real events that happened in the past. You'll see that in the pilot episode, that it starts about two years ago."
Sorkin went on to suggest that the show will not necessarily be to everyone's tastes, according to Deadline.
He commented: "I know for sure not everyone is going to love this. A lot of great storytelling is happening on television, and you've got to look around for the good stuff."
The Newsroom lead Jeff Daniels recently praised Sorkin's dialogue, calling his writing "very much like a piece of music".
Daniels stars in the series as a cable news network anchor, with Emily Mortimer, Dev Patel, Olivia Munn, Jane Fonda, John Gallagher Jr and Allison Pill also in the cast.
