The first season of Silo was not even finished when Apple renewed the sci-fi show for another volume, and Silo season 2 was even bigger and more shocking than its predecessor. Silo is based on a series of novels by author Hugh Howey, and tells the story of thousands of people living in a giant silo that acts as an underground bunker. Residents of the silo are forbidden from exploring the outside world. Rebecca Ferguson stars as an engineer named Juliette who begins investigating what happens to people who attempt to leave the silo and how the residents are controlled.
Silo premiered on Apple TV Plus on May 5, 2023, and the Silo season 1 finale became available on the streaming platform beginning June 30, 2023. Since Silo's debut, the show has developed a loyal following and received positive reviews from critics. Trends in TV change frequently, and there has been a focus on producing miniseries that only receive one season over stories that take place over multiple seasons. Silo being renewed for season 2 signaled just how big of a hit it is for Apple TV Plus and how much faith the streaming platform has in the adaptation.
