There are two different candidates for the video game console with the longest lifespan, from official introduction to discontinuation, and which one holds the distinction depends on one's metrics.

In terms of support from its original developer, the longest-lasting video game console is the Famicom, the Japanese version of the Nintendo Entertainment System. The Famicom was introduced in 1983 and remained on store shelves until 2003, lasting twenty years on the market.

However, when counting support from third party manufacturers, the distinction instead goes to the Sega Master System. While Sega incrementally discontinued the device between 1991 and 1994 depending on the region, Brazilian manufacturer Tectoy received a license from Sega to continue manufacturing clones of the Master System due to its high popularity in Brazil. These clone consoles continue to be manufactured in the present day, decades after the original Master System's launch in 1985.
