13 Reasons Why (stylized onscreen as TH1RTEEN R3ASONS WHY) is an American teen drama web television series developed for Netflix by Brian Yorkey, based on the 2007 novel Thirteen Reasons Why by Jay Asher. The series revolves around seventeen-year-old high school student, Clay Jensen, and his deceased friend Hannah Baker, who has killed herself after having to face a culture of gossip and sexual assault at her high school and a lack of support from her friends and her school. A box of cassette tapes recorded by Hannah in the lead up to her suicide detail thirteen reasons why she ended her life. The series is produced by July Moon Productions, Kicked to the Curb Productions, Anonymous Content and Paramount Television, with Yorkey and Diana Son serving as showrunners.
Dylan Minnette stars as Clay, while Katherine Langford plays Hannah.

A film from Universal Pictures based on Thirteen Reasons Why began development in February 2011, with Selena Gomez set to star as Hannah, before being shelved in favor of a television series and Netflix ordering the show straight to series in October 2015, with Gomez instead serving as an executive producer.
The first season was released on Netflix on March 31, 2017. It received positive reviews from critics and audiences, who praised its subject matter and acting, particularly the performances of Minnette and Langford.
