Gravity Falls is an American animated television series produced by Disney Television Animation originally for Disney Channel (and then later for Disney XD) from June 15, 2012, to February 15, 2016.
Created by Alex Hirsch, the series follows the adventures of Dipper Pines (voiced by Jason Ritter) and his twin sister Mabel (voiced by Kristen Schaal) who are sent to spend the summer with their great-uncle (or "Grunkle") Stan (voiced by Hirsch) in Gravity Falls, a mysterious town full of paranormal forces and supernatural creatures. The kids help Stan run "The Mystery Shack", the tourist trap that he owns, while also investigating the local mysteries.
On June 14, 2014, it was confirmed that Season 2 would premiere on August 1 and on August 4 of the same year on Disney Channel and Disney XD respectively, with most of the season two episodes airing first on Disney XD, as it is considered the new home for the series. On November 20, 2015, Hirsch announced that the series would finish with its second season, stating that he chose to do it for the show to end with "a real conclusion for the characters". The show culminated with a one-hour finale, "Weirdmageddon 3: Take Back the Falls", that first aired on February 15, 2016.
A 68-hour marathon was broadcast on Disney XD from February 12, 2016, up until the finale on February 15, 2016, with the entire series airing in order. Due to only having 39 episodes before its airing, the show was looped four times to fill the 68-hour slot.
Hirsch has stated he remains open to continuing the series with additional episodes or specials. In February 2018, on the two-year anniversary of the final episode of the show, Hirsch used a cipher to announce Gravity Falls: Lost Legends, a continuation of the Gravity Falls story in a new graphic novel
For their summer vacation, 12-year-old Dipper Pines and his twin sister Mabel are dropped off from their home in Piedmont, California to the fictitious town of Gravity Falls, Roadkill County, Oregon to spend the summer with their Great Uncle Stan Pines (often shortened to Grunkle Stan), who runs a tourist trap called the 'Mystery Shack'. Things are not what they seem in this small town, and with the help of a mysterious journal that Dipper finds in the forest, they begin unraveling the local mysteries. With appearances from Wendy Corduroy, Mystery Shack cashier; Soos Ramirez, friend of Dipper and Mabel and handyman to Grunkle Stan; plus an assortment of other characters, Dipper and Mabel always have an intriguing day to look forward to.
