, originally short for Service Games and officially styled as SEGA, is a Japanese multinational video game developer and publisher headquartered in Tokyo, Japan, with multiple offices around the world. Sega developed and manufactured numerous home video game consoles from 1983 to 2001, but the financial losses incurred from their Dreamcast console caused the company to restructure itself in 2001, and focus on providing software as a third-party developer from then on. Nonetheless, Sega remains the world's most prolific arcade producer, with over 500 games in over 70 franchises on more than 20 different arcade system boards since 1981.

Sega is one of the major music genres of Mauritius, the others being its fusion genre Seggae and Bhojpuri songs. It has origins in the music of slaves on the island, and is usually sung in creole. Sega is also a popular music on the islands of Agalega and Rodrigues as well as Réunion and Seychelles, though the music and dances differs and it is sung in these islands' respective creole languages. In the past, the Sega music was made only with traditional instruments like ravanne and triangle, it was sung to protest against injustices in the Mauritian society, this particular version of the Sega is known as Santé engagé.
