Nintendo Switch - the longest-lasting home (?) console in Nintendo's history
It's a hybrid. But it is still counted as a home console.
The VGC portal compared the time intervals between the releases of Nintendo consoles. Only the release date of a new generation was considered.
Since its release on March 3, 2017, the Nintendo Switch has been on the market for 2695 days. The previous record belonged to the Famicom (2686 days), which was replaced by the Super Famicom.
The shortest lifespan was with the Wii U - between the console's release and the appearance of the next system, 1566 days passed.
However, the Game Boy holds the record for Nintendo among all consoles (including handhelds). The console remained on the market for 4352 days until the Game Boy Advance was released.
Nintendo's most successful system in history - the Nintendo DS - was on the market for 2288 days.
