Ben Barnes and Jimmi Simpson of HBO's "Westworld." HBO "Westworld" is open for business for another year. HBO has renewed the sci-fi drama for a second season.

The network also announced on Monday the renewals of new comedies "Divorce" and "Insecure."

“I am thrilled to announce the pickup of our three fall series, all of which have distinctive, original voices,” HBO Programming President Casey Bloys said in a statement. “Critics and viewers alike have welcomed 'Westworld' and 'Insecure,' as well as the return of Sarah Jessica Parker to the network after 12 years with 'Divorce.'”

According to HBO, "Westworld" is averaging 11.7 million total viewers, which is more than “Game of Thrones” and “True Detective" in their first seasons. Both "Divorce" and "Insecure" are averaging 4.4 million and 3.2 million viewers, respectively, which is on par with other HBO half-hour comedies “Veep” and “Girls.”

Presumably the three shows will be back in fall 2017, but HBO didn't give any information on return dates.

But according to The Hollywood Reporter, "Westworld" may not be back until 2018.

"'Westworld' is such a big, ambitious show. I don't know if it will be fall of 2017 or into '18," Bloys told THR. "That will depend as we get up and running. With 'Westworld,' because the production is such a big endeavor, I don't exactly know when [it will premiere] yet. I can't speculate other than to say it'll either be '17 or '18. Probably more like '18 and half-hours ['Insecure' and 'Divorce'] in '17 but we're a year away so let's see how it goes."

"Westworld" is considered HBO's potential new series to replace drama hit "Game of Thrones," which has two seasons left. The new sci-fi show stars Anthony Hopkins, Thandie Newton, Evan Rachel Wood, and James Marsden.

Issa Rae stars on "Insecure," about an awkward black woman trying to find her place in the world. It's cocreated by Rae and Larry Wilmore.

On "Divorce," Parker plays a woman who is in the throes of ending her marriage to her husband, played by Thomas Haden Church.
