Cyworld ( ) is a South Korean social network service operated by SK Communications ( ), a subsidiary of SK Telecom ( ).
Members cultivate relationships by forming Ilchon ( , Hanja: 一寸) or "friendships" with each other through their minihompy.
Avatars and "mini-rooms", small, decorate-able, apartment-like spaces in an isometric projection, also feature. All of this can make for a Sims-like experience.
The "Cy" in Cyworld could mean "cyber" but is also a pun on the Korean word for relationship ( 'between').
Revenue is generated through the sale of dotori ( ), or "acorns", which can then be used to purchase virtual goods, such as background music, pixelated furniture and virtual appliances.
Cyworld also has operations in China and Vietnam.
