Abstract: In a content providing apparatus, a storage unit stores a virtual space generated based on geographical information of a real space, a structure object corresponding to a structure in the real space, owner information on a proven owner of the structure object, and content information associated with the owner information. The virtual space, the structure object, and the user object associated with position information on a user terminal in the real space are displayed on a display unit of the user terminal. When the position information on the user terminal indicates the user terminal's being present within a given range from the structure in the real space and a request for the content is made from the user terminal, a content providing unit provides the content in such a way as to allow the user terminal to use the content. An incentive giving unit gives an incentive to the owner.
