Wikipedia led to the gradual shutdown of Nupedia. Jimmy Wales decided to stop paying Sanger in December 2001. Sanger then left both Nupedia and Wikipedia. After Sanger left, Nupedia became even less noticed than Wikipedia. As Nupedia was used less and less, the idea of changing its articles into Wikipedia articles was sometimes proposed. However, it was never done. After it closed down, Nupedia's articles were moved in to Wikipedia.
