Next week marks a rite of spring: The upfronts, or the presentation of the broadcast networks' fall TV slates to advertisers, beginning May 15.

But first, comes the culling of the herd.

This week, programming execs are deciding the fates of on-the-bubble shows, either giving underperformers another season to find an audience or casting them off to make room for what they hope will be new hits.

The main factors in their decisions: Ratings trends, creative momentum, profitability and the network's ownership stake.

In a surprise move Saturday, NBC took a page from the script of this year's top Save Our Shows vote-getter, went back in time and reversed its cancellation decision. It's bringing the time-travel drama back for 10 episodes next summer. It also renewed another favorite, Blindspot. It has yet to decide what to do with Chicago Justice.  Later in the day, CBS renewed the Sherlock Holmes drama Elementary, which finished second in the poll, for a sixth season.

In other Save Our Shows news, ABC has canceled Last Man Standing and American Crime, Fox has renewed The Exorcist and CBS has canceled 2 Broke Girls after six seasons. ABC's immigrant comedy Fresh Off The Boat, which finished mid-pack in this year's poll, was granted a fourth season Friday.

Check the list below to see where your favorite shows stand.

Note: All the prime-time series are grouped in one of three categories — already renewed or very likely to return; on the bubble and in need of your vote; and on death's door or already canceled.
