Ab Fab started as a BBC sitcom in 1992, created by Jennifer Saunders, with its roots in a French and Saunders sketch. The show ran five series across the 1990s and early 2000s, earning a lasting fan base and several specials. Details:

• Original run: 1992–1996 for the first three series and a two-part finale, followed by new series and specials in the 2000s. The initial pilot and subsequent seasons established the core characters Edina Monsoon and Patsy Stone.
• Cultural note: In the U.K., it’s commonly referred to as “Ab Fab.”
