The process of finding new footing continued for Disney into 1961. The company paid off its existing loans, debuted Wonderful World of Color on NBC on September 24th (and introduced America to Professor Ludwig von Drake), and released its first truly new animated film since Snow White and the Seven Dwarfs to theatres. Disney also ended their popular series of Donald Duck cartoons this year, against the backdrop of general changes in America's filmgoing habits. Nevertheless, they also acquired the rights to the Winnie the Pooh character. The first draft of Mary Poppins was finished, and it is in this year that the film Saving Mr. Banks is set, fictionalizing the challenges of working with Pamela Travers. Disney was setting itself up nicely for its new-new era.
