Girls is an American television series that premiered on HBO on April 15, 2012.
 Created by and starring Lena Dunham and executive produced by Judd Apatow, "Girls" is a comedy-drama following the lives of four young women living in New York City.
 The show's premise and major aspects of the main character—including being cut off financially from her parents, becoming a writer and making unfortunate decisions—were drawn from Dunham's own life.
 Apatow said he was drawn to Dunham's imagination after watching her independent feature film "Tiny Furniture" (2010), and added that "Girls" would provide men with an insight into "realistic females".
The Fox sisters were three sisters from New York who played an important role in the creation of Spiritualism: Leah (1831–1890), Margaret (also called Maggie) (1833–1893) and Kate (also called Catherine) Fox (1837–1892).
 The two younger sisters used "rappings" to convince their much older sister and others that they were communicating with spirits.
 Their older sister then took charge of them and managed their careers for some time.
 They all enjoyed success as mediums for many years.

Georgia is a 1995 American independent film starring Jennifer Jason Leigh and Mare Winningham.
 In the film, Leigh played Sadie Flood, a punky barroom singer who has a complicated, jealous but loving relationship with her older sister, Georgia, played by Winningham.
 Georgia is a successful, talented and well-adjusted folk music singer and a happily married mother of two.
 Sadie is passionate but self-destructive and untalented.
 While she seeks fame, she destroys herself through drug abuse.
 Although the movie focuses largely on Sadie, it was apparently titled "Georgia" because Sadie defines her own identity so much through her older sister.
