The last episode of the first season of all three of Aaron Sorkin's TV shows (The West Wing (1999), Sports Night (1998), and Studio 60 on the Sunset Strip (2006), as well as the series finale of "The Newsroom" (2012) are entitled "What Kind of Day Has It Been?"
The character "Margaret 'Maggie' Jordan" was based on the real-life Margaret Judson, an MSNBC insider who started out as an NBC Page and worked her way up through the ranks in a real-life network newsroom. Judson was hand picked and eventually cast by Aaron Sorkin for the role of "Tess Westin." Judson also worked with the writing team as a special consultant.
Aaron Sorkin hired conservative media consultants for the second season to help him represent "every part of the ideological spectrum," thus giving the show "a political perspective that I don't have."
Jeff Daniels won his Leading Actor Emmy Award the night before he started filming Dumb and Dumber To (2014).
In season 3, Equatorial Kundu, the fictional country where 38 deaths occur, is the same fictional West African country used by Aaron Sorkin in the West Wing.
