Information such as advertisements (26) or news is selected for a user based on the attributes (23) that the user has input to build (22) their avatar (21) or avatar environment. The advertisements may be selected for presentation (24) using one user's attributes or attribute history. Alternatively, the user's attributes may be used to proximity search for matching user attributes and those are used to select the advertisement. In another embodiment, the attributes are used to affect the behaviour of an agent representing the user.
