Netflix announced that Sense8 would not be renewed for a third season due to low ratings that didn't justify the show's massive budget (at least $9 million per episode). In response, fans created petitions and a hashtag calling for the show to be uncancelled, as well as threats to cancel their Netflix subscriptions en-masse. The backlash did succeed to some extent - although Netflix wouldn't green-light a third season, they have allowed for a two-hour long special to bring closure to the seriesnote Since the service depends less on ratings than simply pure subscription numbers for its money, they're very motivated to ensure their original programming will have decent closure even if it has to end before the crew was ready
White Rabbit Project has been taken out to the back and shot. Grant Imahara claims that Netflix refused to renew the series for a second season because they expressed that they wish to invest more in scripted dramas that are binge-watchable (for example, Stranger Things and Black Mirror).
After season 4 of Degrassi: Next Class ended in Summer 2017, there was no news or updates on the show for over a year. There were rumors that Netflix was trying to retool the show with a completely new cast with some American actors and different tone, much like their premiere teen drama 13 Reasons Why. In September 2018, Stefan Brogen finally confirmed that the show was canceled.
The Netflix Marvel shows (Daredevil (2015), Jessica Jones (2015), Luke Cage (2016), Iron Fist (2017), The Defenders (2017), and The Punisher (2017)) were subject to this from October 2018 through February 2019. Many speculated that Netflix cancelled the shows because their existing partnership with Marvel was ending and didn't want to extend the contracts. The impending launch of Disney+ basically meant the shows were going to be a revenue stream competitor. Speculation also exists that Netflix tried to sabotage the shows by scaling back the show's marketing campaigns.
Netflix cancelled One Day at a Time (2017), citing low viewership. It was rescued by Pop TV....where it was canceled AGAIN.
Netflix did not do a very good job of handling Twelve Forever. Though initially ignored by Cartoon Network, which is where the pilot was originally pitched at, Netflix later picked up the series but quickly experienced a Troubled Production involving repeated Schedule Slipnote its release was delayed a total of three months after its completion for currently vague reasons and little-to-no advertisementnote such as the fact that the first season was released on the site with no warning whatsoever. Making matters worse was the show being Overshadowed by Controversy with the creator, Julia Vickerman, being caught making pederastic comments on her social media, as well as the original studio who made the show going under. Netflix ultimately canned the show only after just one season note It wasn't cancelled per se, but there won't be a second season.
Netflix also screwed over Care Bears & Cousins, although this could largely also be due to Executive Meddling from American Greetings (who rebooted the franchise just after the premiere of the second season of the show, and made Unlock the Magic and put it on Boomerang in the US and Tiny Pop in the UK instead). Likewise, Netflix let their rights for Care Bears: Welcome to Care-a-Lot expire and Hulu picked up the rights.
Tuca & Bertie was in a similar situation as Twelve Forever. Little advertising from the main Netflix accounts (though still more than Twelve had gotten), and despite high praise from reviewers, it was not renewed. A year later, the show would be rescued by [adult swim] for a second season.
Kipo and the Age of Wonderbeasts didn't get any promotion whatsoever. The show basically relied entirely on word of mouth and its positive reviews to get traction.
The Hollow similarly didn't have much advertising, and there was a 2-year gap between seasons 1 and 2. It ended after 2 seasons in 2020.
