On what date did How I Met Your Mother premiere on CBS?

How I Met Your Mother premiered on CBS on September 19, 2005. Its first episode, titled “Pilot,” introduced Ted Mosby and the group of friends whose lives drive the nine-season sitcom.

The premiere begins with Future Ted in 2030 telling his children how he met their mother. The story then moves back to 2005, where the younger Ted decides he is ready to find a soulmate after his best friend Marshall proposes to Lily. Ted's meeting with Robin becomes the first major turn in the long-running story.

The series was created by Carter Bays and Craig Thomas and starred Josh Radnor, Jason Segel, Cobie Smulders, Neil Patrick Harris, and Alyson Hannigan. Bob Saget narrated as Future Ted, adding the voice that connects the show's different time periods.

A frequent date mix-up comes from the show's other milestones. May 15, 2006, was the season-one finale, while March 31, 2014, was the series finale. September 18, 2006, was the season-two premiere, not the original CBS debut.
