Mix Nine was a South Korean survival reality show broadcast on JTBC. In the show, YG Entertainment founder and producer Yang Hyun-suk traveled to music agencies across Korea to find up-and-coming K-pop stars. Throughout the episodes, contestants were progressively eliminated, culminating in a competition between a team of the final nine boys and one of the final nine girls. The winning team was to debut as idols, but their debut was ultimately cancelled following contract disputes between YG Entertainment and the contestants' respective agencies.
