ZTV is a TV studio in the Yu-Gi-Oh! manga.
Jonouchi took part in the game show "Get the Million" on ZTV. The producer tried to rig the competition so that Jonouchi couldn't win the ¥1,000,000, but Dark Yugi spilled paint on the buttons, making him unable to tell which button rigs the wheel. Although Jonouchi won, the check turned out to be worthless after the studio went out of business.
