An advertisement service allows advertisers to obtain a right to provide an advertisement to a mobile device that is located within or nearby a particular geographic region. For instance, the advertisement service may map one or more entities (e.g., retailers, schools, museums, etc.) to a geographic region at which these entities are located. The advertisement service provides an offer to one or more advertisers to provide an advertisement to a mobile device located within or nearby one of these geographic regions. Based on responses received to the offer, the advertisement service provides information to the mobile device for display of an advertisement. |
