Game of Thrones ended in 2019 because it reached the conclusion of its storyline. The show is based on the "A Song of Ice and Fire" series of novels by George R. R. Martin. By the end of season 7, the television series had already overtaken the novels, as the last two books of the series hadn't been published yet. Therefore, the storyline for the final season was a result of discussions between the series' showrunners and Martin. Even before the show started, the creators David Benioff and D.B. Weiss aimed to tell a complete story that wouldn't drag out unnecessarily. They envisioned that the series would end around the 70-hour mark. Eventually, the series ended up being 73 hours in total length, achieving relatively close to their original plan. While some fans expressed dissatisfaction with the final season, particularly with the pacing and handling of certain character arcs, the fact remains that 2019 was planned as the series' conclusion year. Nothing expedited its ending; it was simply the time to conclude the epic saga as envisaged by the creative team behind the show. In summary, Game of Thrones ended in 2019 because its storyline had been fully explored and the creators felt it the right moment to bring the epic fantasy series to a close. This ensures that viewers who look back or rewatch the series can enjoy a complete storyline from beginning to end, without the storyline being unnecessarily dragged out or cut short.
