The Sega Master System (SMS for short) (Japanese: マスターシステム), is an 8-bit cartridge-based gaming console manufactured by Sega.

For information on the earlier Japanese version of the console, see SG-1000 Mark III.



The SG-1000 Mark III came after the SG-1000 Mark I and SG-1000 Mark II. It was released in Japan on October 20, 1985. The mascot of the system was Alex Kidd.

The system was redesigned and was sold in the United States under the name Sega Master System in June 1986, one year after the Nintendo Entertainment System was released. The console sold for $200. The Master System was then released in other places, including a second release in Japan in 1987 under its new name.

Though the Master System was more technically advanced in some ways than the NES, it did not attain the same level of popularity among consumers in the United States. Its lack of success in the U.S. has been attributed to various causes, among them the difference in game titles available for each platform, and the slightly later release date of the Master System. The licensing agreement that Nintendo had with its third-party game developers may have had an impact as well; the agreement stated, in effect, that developers would exclusively produce games for the NES. The Master System sold 125,000 consoles in the first four months. In the same period, the NES would net 2,000,000.

Nintendo had 90% of the North American market at the time. Hayou Nakayama, then CEO of Sega, decided not to use too much effort to market the console in the NES-dominated market. In 1988, the rights to the Master System in North America were sold to Tonka, but its popularity continued to decline. The move was considered a very bad one, since Tonka had never marketed a console and had no idea what to do with it.

In 1990, Sega was having success with its Sega Mega Drive/Sega Genesis, and they took back the rights from Tonka for the SMS. They designed the Sega Master System II, a newer console which was smaller and sleeker but which, to keep production costs low, lacked the reset button and card slot of the original. Sega did everything in its power to market the system, but nothing came out of it.

By 1992, the Master System's sales were virtually nonexistent in North America, and production ceased. Sales were poor in Japan as well, due to the dominance of the main competitor from Nintendo, the Nintendo Family Computer.

In Europe, Sega marketed the Master System in many countries, including several in which Nintendo did not sell its consoles. It had some success in Germany, where it was distributed by "ariolasoft" since winter 1987. The Europeans had garnered lots of third party support for the SMS, and as a result, it was able to outsell the NES in Europe. Nintendo was forced to get licensing for some popular SMS titles in that market. The Master System was supported until 1996 in Europe. It was discontinued so that Sega could concentrate on the new Sega Saturn console.

Sales of the SMS in Australia were not as strong as the NES enjoyed there, however the SMS was able to gain greater market share than it had in North America.

Brazil was one of the SMS' most successful markets. It was marketed in that country by Tec Toy, Sega's Brazilian distributor. A Sega Master System III (and even a semi-portable SMS VI) had been released in that market, and several games had been translated into Portuguese. The characters in the said games had been modified so that they appealed to Brazilian audiences (for example, Wonder Boy in Monster Land featured Mnica, the main character from a popular children's comic-book in Brazil, created by Maurcio de Sousa). Brazil was also where the first several Sonic the Hedgehog Game Gear titles started out. Tails, one of the characters, made his worldwide debut in Sonic the Hedgehog 2 for the Master System. That title would later be ported to the Game Gear in other markets.

Later in its life in Brazil, Game Gear games had been ported to the Master System, and several original Brazilian titles were made for the system. Tec Toy also produced a licensed version of the wildly popular fighting game Street Fighter II for the Master System. Despite the limitations of the console, the game turned out to be pretty good. The console production was familiar to the Brazilians, which explains the success in that market. During the Master System's final days in Brazil, games had been marketed for small children.

The Sega Master System is still being produced in Brazil. The latest version is the "Master System III Collection". It uses the same design as the North American Master System II (Master System III in Brazil), but is white and comes in two versions: one with 74 games built-in and another with 105 games built-in on an internal ROM. But in Brazil it's hard to find the 3D Goggles, the Light Phaser Pistol and even the cartridge, leaving Brazilians only with the built-in games.

Overall, the SMS was mildly successful worldwide, but failed to capture the Japanese and North American markets. Sega would learn from its mistakes and made the Sega Mega Drive wildly popular in Europe and Brazil, and the North American equivalent, the Sega Genesis, popular in that market. The failure of the SMS meant the success of the Mega Drive and Genesis.
