Sega Master System

Master System is a home video game console made by Sega in 1986. It is Sega's second home game console after the slighty unsuccessful SG-1000.

Trivia
The best-selling game is Alex Kidd in Miracle World at 5 million copies. It is obvious because the game was built in the second version.

The console was discontinued in 1996.

The console sold 10 million units.

Since it's release in 1986, it pushed Sega to becoming one of the best game companies.
