CBS Renews Under the Dome, Extant

Under the Dome Extant Renewed

Two of CBS’ summertime dramas will be back for additional seasons.

The Eye network announced on Thursday that it has picked up the Stephen King-inspired Under the Dome for a third season, while the Steven Spielberg-produced, Halle Berry-fronted Extant will be back for Season 2.

Dome was a bona fide hit when it first bowed in June 2013, drawing 13.5 million total viewers and a 3.3 demo rating. Season 2 premiered to a more modest 9.4 mil/2.1, while its finale drew 7.5 mil/1.8 (and an average grade of “C+” from TVLine readers).

With Live+7 DVR viewing factored in, Dome was the summer’s No. 1 scripted series, averaging 11 million viewers and a 2.7 rating.

Extant premiered this past June to 9.6 million viewers and a 1.6 rating, but by its Sept. 17 finale — and following some schedule-shuffling — had slipped to 5.4 mil/1.0. TVLine readers gave the season as a whole a grade of “C+.”

Helping offset the two series’ pricetags, CBS has a deal with Amazon Prime — for a reported $900,000-per-episode, for each show — to be the exclusive home to streamed episodes.
