I'm including all regions, so it's both halves of your definition. In Japan the console itself was still being produced in 2006, so you would have walked into a store and seen new Dreamcasts for sale alongside PS3.    Sega Genesis was dead in the USA by the late 90's, but it lived on in Brazil past 2000.
