List of Gravity Falls episodes

[1] A pilot for Gravity Falls was pitched to Disney Channel in 2010 which led to the series being green-lit.

Prior to the creation of Gravity Falls, Alex Hirsch was helping to develop the Disney Channel animated series Fish Hooks, when Disney contacted him and asked him if he would like to pitch his own animated series to the network, which Hirsch accepted.

[8] Disney commissioned Hirsch to create an eleven-minute low-budget animated pilot[2] for Gravity Falls which he later described as "a short version of Tourist Trapped".

[9] On December 9, 2010, it was announced that Disney Channel had greenlit Gravity Falls for a full series based on the pilot, which was originally slated to premiere in spring of 2012.

[3] The pilot was never broadcast on television and for many years Hirsch had no intention of releasing it to the public.
