Nintendo are killing off Netflix on their Wii games console on 31st January 2019 as they close down the last parts of their online service. Users have been unable to download the Netflix ‘channel’ since the end of July 2018 but the services are still working for now. However, all streaming media (including Amazon Prime, Hulu etc) will end when the Nintendo Wii Shop channel closes on 31st January 2019. The Wii was released in November 2006 so users have had a good run of 12 years services.
This does not affect the Wii U.
