* The show has had multiple "revivals": Futurama originally aired from 1999 to 2003, then was revived for four more seasons from 2008 to 2013. In 2019, the show returned for a 20-episode season, which was the most recent.
* There's been no official announcement regarding ending the show: While there haven't been any new seasons greenlit, the door isn't closed. The 2019 revival was a huge success, and creators Matt Groening and David X. Cohen have expressed interest in continuing the show in the future.
* It largely depends on demand and production circumstances: The show's future hinges on factors like viewership numbers, the availability of the creative team, and the willingness of Hulu (the streaming platform) to continue funding.
In short, Futurama isn't permanently over, but it's currently on hold. Fans are hopeful for a future revival, but nothing is certain at the moment.
