When Little House on the Prairie made its debut, it was a huge hit with viewers. But believe it or not, the show was in danger of cancellation by the time it hit its second season!
In an attempt to save the show, NBC moved it from Wednesday nights to a new time slot on Monday nights. The move ended up saving the show, and the ratings improved in the third season.
But by the time the fourth season was coming to a close, NBC was contemplating canceling the the show again. However, the ratings held firm, and the show went on to have another season, and another, and another.
