The Disney Post-Renaissance (also known as Disney's Second Dark Age or Disney's Experimental Era) refers to an era in the Disney Animated Canon beginning roughly in 1999 and lasting until 2008 when there weren't as many critically or financially successful animated films compared to the Disney Renaissance. While a few films during this time period enjoyed critical and commercial success, other films released during this period garnered poor reception, or performed poorly at the box office. This era is particularly notable for witnessing the decline of traditional 2D animation in the face of stiff competition from DreamWorks and Blue Sky, the departure of CEO Michael Eisner and subsequent appointment of Bob Iger to the post, the purchase of Pixar in 2006, and the hiring of John Lasseter and Ed Catmull to oversee all animation at the company. However, most of these films were financially successful at the box office and a few films were even nominated for several film awards, winning a few of them.
