From The Hollywood Reporter:
The network has renewed the summer drama about a town encapsulated by a mysterious dome for a second season, CBS announced Monday at the Television Critics Association's summer press tour. The drama will return with another batch of 13 episodes in summer 2014.
The drama, an adaptation of Stephen King's best-seller of the same name, hails from Steven Spielberg's Amblin Entertainment, CBS Television Studios and DreamWorks Television and was picked up straight to series after initially being developed for CBS corporate sibling Showtime.
"We're excited to tell more stories about the mystery of the dome and the secrets in Chester's Mill, and are thrilled to have the master storyteller himself, Stephen King, tell the first one of next season," CBS Entertainment president Nina Tassler said in a statement announcing the news.
