US Patent 7515136 Collaborative and situationally aware active billboards

A method of collaborative interactions with billboards includes receiving a request, by a billboard network manager, from an advertisement company to display synchronized interactive advertisements and video games on billboards in an area, inviting users in the area to participate in the advertisements and video games through the billboards and mobile devices of the users via a network, checking registration of the users to participate in the collaborative interactions with billboards, and checking a volume of the users in the area for appropriate synchronized advertisements and video games. If the volume of users is appropriate for synchronized advertisements and video games, then the billboard network manager displays the synchronized advertisements and video games, and continues to track the volume of the users in the area. If the volume of users is not appropriate for synchronized advertisements and video games, then the billboard network management reconfigures synchronized billboard content for more appropriate advertisements and video games by one of randomly changing a content, and propagating and extending through synchronized billboards a particular content of some billboard section that brought more interest from the users.
