"The New Adventures of Mighty Mouse and Heckle & Jeckle," which aired in the mid-1980s, was canceled primarily due to low ratings and a shift in audience preferences towards different styles of animation and storytelling. The show struggled to compete with more popular cartoons of the time, and although it had a creative approach with updated animation and humor, it did not capture a substantial viewership. Additionally, the changing landscape of children's television programming contributed to its eventual cancellation.
