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 the main character, Ted Mosby, and his group of friends in New York City's Manhattan. As a framing device, Ted, in 2030, recounts to his son, Luke, and daughter, Penny, the events from September 2005 to May 2013 that led him to meet their mother. How I Met Your Mother was a joint production by Bays & Thomas Productions and 20th Century Fox Television, and syndicated by 20th Television (now Disney-ABC Domestic Television).

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 unique 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. In 2010, Alyson Hannigan won the People's Choice Award for Favorite TV Comedy Actress. In 2012, seven years after its premiere, the series won the People's Choice Award for Favorite Network TV Comedy, and Neil Patrick Harris won the award for Favorite TV Comedy Actor twice.
