Scheduling a network's shows and timeslots is a balancing act of identifying and investing in good programs and scheduling them to best reach the intended audience.
That job falls to network programming directors, who also must consider what other networks are showing and when. It's a competitive game of TV programming chess, with each network trying to position its shows for the highest possible viewership.
In attempts to win viewers and beat-out their competition, many networks either make last-minute scheduling changes or decide not to release their schedules until nearly air-time. It's why some printed programming guides, including TV Weekly, seemingly have outdated or incorrect listings.
In our on-going effort to provide you with fast-and-easy access to the shows you love, TV Weekly provides updates from the networks which most frequently change their programming schedules. Check this site weekly for updates.
