Platform: Sega Master System/Mark III

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.

Due to South Korea banning Japanese cultural imports at the end of World War II, the Master System was distributed by South Korean company Samsung, and was named the Gam*Boy.

Many releases of the Master System included games in the console's BIOS that could be accessed by booting up the system without a cartridge in it. Some releases included multiple games, with one in Brazil boasting 131, but most included one of the following:

• Snail Maze
• Hang-On
• Hang-On & Safari Hunt
• Missile Defense 3-D
• Alex Kidd in Miracle World
• Sonic the Hedgehog

A graphic board peripheral was in development for the Master System which was going to be released in 1987. Players could draw using a fully editable 16 colors bitmap with a 176x144 pixel area. The software for the peripheral was being designed by Kazuo Wakihara who had worked on Columns. The graphic board would've also been compatible with the Genesis.

In 2018, rapper Soulja Boy attempted to sell his own line of video game consoles, called the SouljaGame line, sold for $149.99 for a console and $99.99 for a handheld. Advertising claimed that the consoles would be compatible with a variety of consoles' games, including modern platforms like the PlayStation Vita, Nintendo 3DS, and Nintendo Switch. They obviously did not have such compatibility, and were rather a generic retro emulator console one could find on small business-oriented retail websites such as Wish and AliExpress loaded with pirated and modified games sold at a markup. Game libraries featured included the Neo Geo, NES, SNES, Game Boy, Game Boy Color, Game Boy Advance, Sega Genesis, Sega Master System, Sega Game Gear, and PlayStation. The only difference from these pre-existing consoles is a photograph of Soulja Boy printed onto the box. He would eventually stop selling SouljaGame consoles, with the website for the console redirecting to Nintendo's 3DS website.
