Dateline NBC is a weekly American television newsmagazine/reality legal show that is broadcast on NBC. It was previously the network's flagship news magazine, but now focuses mainly on true crime stories with only occasional editions that focus on other topics. The program airs Fridays at 10:00 p.m. Eastern Time (9:00 p.m. Eastern for special two-hour editions) and on most Sundays, outside the NFL season, at 7:00 p.m. Eastern Time. Special Saturday editions also occasionally air during the fall and winter months. Two-hour feature-length editions sometimes air on any given scheduled evening, often to fill vacancies in the primetime schedule on the program's respective nights due to program cancellations.
