#11: The Show Nearly Got Canceled Before Becoming a Long-Running Hit
The series started strong, earning big ratings in its first season. But when the second season aired, viewership dropped sharply, and NBC seriously considered canceling it. To save the show, the network moved it from Wednesday to Monday nights, hoping to reach a bigger audience.
