The 2000s was the fourth decade in the industry's history. It was a decade that was primarily dominated by Sony , Nintendo , newcomer Microsoft , and their respective systems. Sega , being Nintendo's main rival in the 1980s and 1990s, left the console market in 2002 in favor of returning to third-party development, as they once were.
