What was the first home video-game console to use interchangeable cartridges, released by Fairchild in 1976?

The Fairchild Channel F was the first home video-game console to use interchangeable cartridges.

Fairchild Semiconductor released the system in North America in November 1976 as the Fairchild Video Entertainment System. Its cartridges, called Video Entertainment System modules, stored complete games that users could swap into the console.

Earlier systems generally contained built-in games or used removable overlays and accessories rather than programmable cartridges. The Channel F used a Fairchild F8 microprocessor, an important technical step for home consoles.

Atari followed with the Video Computer System in 1977, later renamed the Atari 2600. Because the Atari system became far more successful, it is sometimes mistakenly credited with inventing the cartridge console, although Fairchild's system came first.
