From Wikipedia: Once Upon a Time is an American fantasy adventure drama television series that aired on ABC from October 23, 2011 to May 18, 2018. The first six seasons are largely set in the fictitious seaside town of Storybrooke, Maine, with the characters of Emma Swan and her 10-year-old son, Henry Mills, as the leads — whilst the seventh and final season takes place in Seattle, Washington, in the fictitious neighborhood of Hyperion Heights, with a new main narrative led by adult Henry Mills, his wife Ella (Jacinda), and their daughter Lucy. The show’s more notable characters are based on original Disney characters from The Walt Disney Company and popular Western literature, folklore, Greek mythology, and fairy tales. The family of Snow White and Prince Charming from Disney’s Snow White and the Seven Dwarfs are the main family featured in the series.

Once Upon a Time was created by Lost & Tron: Legacy writers Edward Kitsis and Adam Horowitz. A spin-off series, Once Upon a Time in Wonderland, consisting of 13 episodes which followed the peculiar character from the 1865 novel Alice’s Adventures in Wonderland by Lewis Carroll, premiered on October 10, 2013 and concluded on April 3, 2014.^[2]
