The recognizable modern phenomenon emerged in the late 1990s around commercial network games, especially Ultima Online shard emulators and the bnetd Battle.net replacement.",
  "popularization_summary": "Private servers spread through late-1990s Ultima Online and Battle.net communities, then grew substantially through early-2000s MMORPG emulator projects. Translations, public source repositories, forums, forks, and regional branches helped projects such as eAthena and MaNGOS travel across North America, Europe, East Asia, Brazil, and other player communities. Comparable public population data are scarce, so no regional popularity ranking is asserted.",
