TARGETED IN-GROUP ADVERTISING

Embodiments of the present invention fill the need of displaying relevant advertisements to members of targeted online groups (or online community groups), whose group members share common interests. The relevant advertisements are provided by advertisers who promote goods and/or services that the targeted online groups are likely to have an interest. The advertisers choose the targeted online groups based on the description of the common interests, focus or background of the online groups, or based on the categories that the online groups are associated. In one embodiment, moderators of the online groups may screen the advertisements before they are displayed on the online group media spaces. By matching interests, focus or background of online groups with products and/or serviced promoted by the advertisers and by moderators screening advertisements, the advertisements displayed would be more likely to be relevant to the members of the online groups.
