Despite being a hit, Gravity Falls season 2 was its last on the Disney Channel — here’s why it ended instead of continuing with Gravity Falls season 3. Created by Alex Hirsch, Gravity Falls was an animated mystery-comedy show which aired from June 15, 2012, to February 15, 2016. The series followed the summer adventures of 12-year-old twins Dipper and Mabel as they were sent to the mysterious town of Gravity Falls, Oregon. Gravity Falls established itself as one of the most influential cartoons of the decade. The show won three Annie Awards, two Emmy Awards, and one BAFTA Children’s Award.
