Typically people think of games like WoW, EQ, and UO as some of the first MMO's.
Nowadays MMOs are mostly instanced.
Meaning instead of having thousands of players in a zone, they have a smaller amount of players spread over many 'instanced' copies of a zone, and those players are all still in a persistent world overall, they just cant be all packed into the same zone.
