"The 100" was cancelled after its seventh season primarily due to declining viewership and the show's natural narrative conclusion. While it had a dedicated fan base, ratings decreased over the seasons, which is a common factor in network decisions to end a series. Additionally, the show's creator, Jason Rothenberg, felt that the story had reached a satisfying conclusion, allowing the series to end on a high note rather than dragging it out unnecessarily. The final season aired in 2020.

"The 100" is a post-apocalyptic TV series based on Kass Morgan's novel series. Set 97 years after a nuclear apocalypse decimated Earth, the story follows a group of 100 teenage delinquents sent back to the planet from a space station called the Ark to determine if it is habitable. As they confront the challenges of survival, they encounter various factions of survivors, grapple with moral dilemmas, and explore themes of leadership, loyalty, and the consequences of their actions. The series delves into the struggle to rebuild society in a harsh environment.

In the TV series "The 100," the original group of 100 juvenile delinquents sent to Earth primarily consisted of teenagers. Throughout the series, many characters face perilous situations, leading to significant losses. By the end of the series, only a handful of the original 100 survive, including characters like Clarke Griffin, Bellamy Blake, and Octavia Blake. The final count of survivors varies as new characters are introduced and others perish, but key survivors from the original group are central to the narrative's conclusion.

"The 100" was removed from Netflix due to the expiration of its licensing agreement. Streaming platforms regularly rotate their content based on licensing deals, and when those agreements end, shows may be taken off the service. Additionally, the series is available on other platforms like HBO Max, which can lead to it being pulled from Netflix as rights are often exclusive to specific services.
