VANCOUVER — It may only be April, but chances are your favourite show’s fate has already been sealed.

It’s decision time for those shows teetering between renewal and cancellation, known in television circles as shows that are on the bubble.

TV’s annual rite of spring — the official fall-season announcements for the U.S. networks — is just around the corner. Now is when the all-important calls are being made about which shows will be back, and which will vanish into rerun heaven.

Ratings alone aren’t the only factor that weigh in the decision. A program’s cost to make, cast contracts, actor availability, DVR viewing, what the networks have in their development pipeline and future upside — whether a struggling show is likely to gain viewers or lose them if it returns — all count toward the final analysis.

This year features more on-the-bubble shows than in recent seasons, partly because so many of the networks’ first-year dramas failed this semester, and partly because there’s no such thing as a sure thing anymore.

Here’s an early look at the networks’ comedies and dramas and their chances of survival:
