Background
Sega has its origins in Standard Games, a Honolulu, Hawaii based American amusement company founded in 1940. Sega, a shortened version of Service Games, would form into a Japanese amusement company in a roundabout way as American legislation banned coin operated gambling games in their primary markets.

Launch
The SG-1000 was launched on July 15, 1983 in Japan on the same day as the Nintendo Famicom launch.

The improved Mark III was launched in October of 1985.

The SG-3000 model added a keyboard, and proved to be more popular in Japan then the original SG-1000.

By 1985 the SG-1000 sold about two million units. The SG-1000 was followed by the Sega Master System.

The Dina game console was also related to the SG-1000.
