According to the show creator Christopher McCulloch, Venture Bros. has been canceled by Adult Swim for a few months now.
Unfortunately, it’s true: #VentureBros has been canceled. We got the highly disappointing news a few months ago, while we were writing what would have been season 8. We thank you, our amazing fans, for 17 years of your kind (and patient) attention. And, as always, We Love You.— Jackson Publick (@jacksonpublick) September 7, 2020
But all hope is not lost. A tweet from the officially Adult Swim Twitter account indicates that we may not have seen the last of the Venture Bros. tv series.
We also want more Venture Bros. and have been working with Jackson and Doc to find another way to continue the Venture Bros. story.— adultswim (@adultswim) September 8, 2020
