Ratings are down and cable subscriptions are shrinking, so what are cable channels to do?

The answer, evidently, is: experiment.

In the latest let’s-give-it-a-whirl move by a cable network, AMC is teaming up with Comcast to offer a new $4.99-a-month upgrade option called AMC Premiere. It’ll allow viewers to watch the latest episode of AMC shows like “The Walking Dead” or “Better Call Saul” without any commercial interruption — meaning they can finish it minutes before viewers watching on traditional cable.

The service will have other bells and whistles to entice would-be subscribers, including bonus scenes and interviews with casts and writers. It will not, however, have past seasons of many of AMC’s shows.

AMC’s president, Charlie Collier, said he hoped the service would attract fans of the network’s biggest shows.
