Though the ratings have fallen quite a bit, CBS renewed Person of Interest for a fifth season. Now we’ve learned that the TV show may be ending.

On Person of Interest, a presumed dead former-CIA agent (Jim Caviezel) and a mysterious billionaire (Michael Emerson) work together to prevent violent crimes in New York City. The rest of the cast includes Kevin Chapman, Sarah Shahi, and Amy Acker.

Deadline reports that, of the CBS shows that have been renewed, POI was the only one to not receive a full season order. At this point, season five will only have 13 episodes.

This is just what happened with The Mentalist a year ago — a series that was also produced by outside studio Warner Bros TV. It was rumored to be that show’s final season many months before the network would confirm it. With this short season renewal, it’s looking like history may repeat itself with POI.

If CBS does indeed cancel POI, the studio could potentially try to find another home for it. While the network doesn’t have a financial stake in the series, the studio does. By the end of next season, there will be 103 episodes — enough for a decent-sized syndication package.

It’s worth noting that the studio already has an off-network deal with WGN America for the series. That cable channel has been producing their own dramas Salem and Manhattan. The ratings have been very tiny for those shows but perhaps WGN could be an option to keep Person of Interest going.

What do you think? Should season five be the end for Person of Interest? Would you watch a sixth season on another channel?
