CBS has renewed its summer event series Under the Dome and Extant, both from Steven Spielberg's Amblin Entertainment Television.
Returning next year for its third season, Under the Dome is based on Stephen King's novel about a small town suddenly and inexplicably cut off from the rest of the world by an enormous transparent dome. The second season of the sci-fi drama was the summer's top scripted series, with 11 million viewers.
Starring Halle Berry, Extant is a mystery thriller about a female astronaut with her family after returning from a year-long space mission with a secret that could change the course of human history. The series won its time slot in its first season, with an average of 8.64 million viewers.
