Supernanny premiered on ABC on January 17, 2005. In each episode of the show, a modern-day Mary Poppins observes how parents handle their day-to-day obstacles with their children. Once she's assessed the pitfalls, she works with the parents, instilling her tried-and-true methods for transforming unwanted behavior. Then, after demonstrating just how well the new style will work and getting unbelievable results from the children, the parents must fly solo with the Supernanny techniques. For several days they try to implement Jo's suggestions, and she revisits them at the end of the program to help keep them on track for the future.
