Abstract: The present invention provides a method of giving gifted goods utilizing communication networks in which gift senders or gift recipients register information on gift recipients related to gift recipients in the server of gift dealers handling gifts. Gift dealers handling gifts provide the information on preferable goods related to preferable gifted goods to gift senders based on the information on gift recipients. Gift senders select and give gifted goods to gift recipients based on the information on gift recipients. Based on the information on gift senders and gift recipients or the messages exchanged by users in the virtual space, the virtual stores are prepared, and by giving the gifted goods in the virtual space, the gifts are given in reality.

Abstract: The present invention provides a method of giving gifts via online networks wherein the users who are gift senders jointly own the virtual space which utilizes communication networks and a symbol defined for each user in the said virtual space and when users exchange messages in the virtual space, gift senders select and give gifted goods for gift recipients.
