The creator of the long-running Adult Swim cartoon series, The Venture Bros. confirmed that the series has been canceled and that its Season 7 season finale is now the series finale of the show.Christopher McCulloch (also known as "Jackson Publick") tweeted out a confirmation of the show's fate on his personal Twitter account on Labor Day evening, noting, "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."RELATED: The Venture Bros. True Villain Has Been Dead the Whole Time (Sort Of)The series, which was written by Publick and Eric Hammer (using the name Doc Hammer), debuted on Cartoon Network's Adult Swim in August of 2004, following a pilot episode that aired in February of 2003. The series was about Dr. Thaddeus "Rusty" Venture, a former boy adventurer like Jonny Quest, who now takes his own two teenage sons, Hank and Dean Venture, on adventures along with their bodyguard, Brock Samson. Venture's arch-nemesis is the butterfly-themed supervillain known as The Monarch.While initially a parody of Jonny Quest (basically, "What if Jonny Quest was a total disappointment as an adult?"), the show grew to become a satire of many different types of action series, including superheroes and G.I. Joe. Most importantly, though, it served as a study in the effect of failure. Nearly all of the major characters on the series are failures of some sort. However, the show is that much more relatable because of it.RELATED: The Venture Bros. Is a Master Class on Character GrowthThe series famously takes a long time between seasons (the first four seasons took place over six years while the next three took place over eight years), so with Season 7 ending in October 2018, most fans weren't expecting the previously announced Season 8 until 2021. Recently, though, in a discussion on Twitter about shows that were canceled too soon, Ken Plume (a friend of the show who did the officially approved art book, Go Team Venture!: The Art and Making of the Venture Bros., back in 2018) tweeted out, "The Venture Bros."

This led to fandom freaking out and sadly, Publick confirmed the sad news on his Twitter on Monday.

While this certainly sounds final, hopefully there is a chance for some sort of resolution for the series to be produced in the future. We have seen a number of other shows get picked up by the various new streaming services after their cancellations recently, including Adventure Time brought back by HBO Max, so hopefully there is still a chance for more stories of Team Venture.
