GoKawiilHisense promises up to eight years of VIDAA OS updates; other TV brands vary widely
A comparison of smart TV software support finds Hisense's VIDAA OS, used mainly in Europe, now backed by a pledge of up to eight years of updates, while Hisense TVs sold in the US typically run Android TV, Fire TV, Google TV or Roku TV instead, leaving support up to those platform owners. Roku, Vizio and Insignia don't publish fixed support periods for their own-brand TVs, though Insignia's use of Amazon's Fire OS implies at least four years of updates based on Amazon's own device policy.
