It used to be that if your favorite TV series was canceled, it was all over but the reruns.
Now fans of canceled programs can pray that one of the online streaming services — Netflix, Hulu, Amazon, Yahoo, YouTube, Crackle and so forth — will step in with a reprieve.
The always endangered cult comedy "Community" will have a sixth season. But not on its ancestral home, NBC, where it was treated as a minor annoyance. Instead, "Community," with a slightly altered cast, will surface on Yahoo Screen.
Similarly, "Longmire," the contemporary western starring Robert Taylor, Katee Sackhoff and Lou Diamond Phillips, will return for a fourth season on Netflix. The show was canceled by A&E in August, despite being the channel's most popular original drama. Because it attracted an older audience, the network considered "Longmire" expendable.
But online outlets don't have to worry about demographics or ratings. The only measurement that matters is the subscriber total. They get paid whether 25 people are watching or 25 million. So even a marginal program may be acquired if it has established a loyal fan base that might sign up just to see it.
Streaming services will even snap up slightly damaged goods. The sitcoms "Selfie" and "Manhattan Love Story" got quick hooks from ABC in the fall — so quick that many completed episodes never made it on air. Enter Hulu, which is letting the shows roll out in their entirety.
The unexpected resurrection of these programs has ignited wild hope among TV viewers that there may be a comeback for some of their old favorites. Several prematurely canceled network series have occasioned ardent fan campaigns for renewal, notably "Firefly," "Veronica Mars," "Jericho" and "Freaks and Geeks."
