Nintendo will shut down the Wii Shop channel on January 30th, 2019, marking the end of an era for the service that first came online for Wii consoles in December 2006. The shutdown will happen gradually: users will still be able to add Wii Points until March 26th, 2018, and still be able to use those points to purchase content until the shop fully goes offline in January 2019.
