This is not a complete history, definitely not. I hope that someday maybe I can write a full background history of SEGA and Sonic, complete with dates and such, but until such time here is a brief history of SEGASonic!
SEGA is a massive video game producing enterprise. It has actually undergone several changes since it's beginning, however. It's actual start was in 1952, a man named David Rose created the company known as "Rosen Enterprises." Rosen was in the US Air Force during WWII. After the war, he moved to Japan where he set up his company. In the beginning, his company imported instant photo booths and coin-op games. Both of these were a well liked by the populace. Rosen Enterprises began to move more towards it's coin op games. They soon went into a merger with a jukebox company known as Service Games. The merger created the company now known as Sega.
