Bosch is an American police procedural streaming television series produced by Amazon Studios and Fabrik Entertainment starring Titus Welliver as Los Angeles Police detective Harry Bosch. The show was developed for Amazon by Eric Overmyer, and the first season takes its inspiration from the Michael Connelly novels City of Bones (2002), Echo Park (2006), and The Concrete Blonde (1994). It was one of two drama pilots that Amazon streamed online in early 2014 (together with The After), and viewers offered their opinions on it before the studio decided whether to place a series order. The seventh and final season was released on June 25, 2021. A spin-off series, Bosch: Legacy, premiered on Amazon Freevee on May 6, 2022, and was renewed for a second season prior to its premiere.
