Abstract: An interactive, computer network based system presents consumers with multimedia brand information via a browser-based interface called the GraffitiWall™. Consumers can use the GraffitiWall™ to modify and display a sponsor's brand information in any way desired. Consumer modifications are immediately communicated to the other member consumers and the advertiser/sponsor. Consumers can rate the GraffitiWall™, or portions thereof, and email the GraffitiWall™. An archive of GraffitiWalls™ is maintained by the system. Consumers participate in online focus groups, one-to-one interviews and discussions, as well as games and promotions pertaining to the brand.
