How I Met Your Mother (often abbreviated as HIMYM) is an American sitcom created by Craig Thomas and Carter Bays for CBS. The series, which aired from September 19, 2005, to March 31, 2014, follows main character Ted Mosby and his group of friends in New York City's Manhattan. As a frame story, Ted (in 2030) recounts to his daughter Penny and son Luke the events from September 2005 to May 2013 that led to him meeting their mother.

The series was loosely inspired by Thomas and Bays' friendship when they both lived in New York. The vast majority of the episodes (196 out of 208) were directed by Pamela Fryman. The other directors were Rob Greenberg (7 episodes), Michael Shea (4 episodes), and Neil Patrick Harris (1 episode).

Known for its non-contemporary structure, humor, and incorporation of dramatic elements, How I Met Your Mother was popular throughout its run. It received positive reviews initially, but reception became more mixed as the seasons went on. The show was nominated for 91 awards and received 21.
