List of Renewed and Canceled TV Shows in May 2016: 'Supergirl' at Risk

It's May, time for TV shows cancellation. Broadcast TV networks will reveal most of their ending programs. However it is not officialy declared the following 5 shows are at a risk.

1. "Nashville" 

The music ABC drama suffers from low ratings (producers are hoping to boost them with guest stars like Kesha and Elton John), but those might not be the only numbers that matter. On the creative side, critics generally agree that the Season 4 isn't as good as the early years, but if "Nashville" is renewed, Variety reports, "My So-Called Life" executive producers Marshall Herskovitz and Ed Zwick will step in as showrunners and try to breathe new life into the music drama.

2. "CSI: Cyber" 

The last remainder of the "CSI" franchise could soon be gone. Ratings are down about 2 million viewers from last year, leaving the CBS drama to average 6.15 million viewers in Season 2. Of those viewers, only 0.92 were in the important age 18-49 demographic. Adding further fuel to cancellation speculation, Ted Danson has already signed on for NBC's new comedy, "Good Place," but the show could continue without him.

3. "Supergirl" 

With an average of 7.68 million viewers throughout the first season, the ratings are not too bad or good. "We heard very positive things, unofficially, from [CBS CEO] Les Moonves," executive producer Ali Adler told TVLine. "[CBS Entertainment President] Glenn Geller and [executive vice president of current programs] Bridget Wiley - they've all been very, very supportive. We're definitely talking about what Season 2 looks like."

4. "Undateable"

Ratings dropped by over 40 percent from last season, and just 2.7 million people tuned in each week. Its NBC's lowest-rated show that has yet to be canceled, so don't expect it to stick around for long.

5. "Sleepy Hollow" 

When it lost leading lady Nicole Beharie, and more than 30 percent of viewers from last year left. With 3 million viewers tuning in, it isn't Fox's lowest rated show, but it's not in great shape. Still, the show managed to retain the majority of Season 3 fans despite moving to Friday's midseason. A steady following on a notoriously low-rated night might lead Fox to renew the show.
