A system and method for mobile interactive communication on a local social networking platform is presented. In particular, the invention comprises a plurality of mobile user interfaces disposed in a communicative relation with at least one local network, such as WLAN, LAN, WIFI hotspot, etc. Each of the mobile devices or interfaces are structured to execute, access or run a social networking application which, in at least one embodiment, is capable of automatically receiving and displaying promotional media communicated by or on behalf of a nearby commercial establishment, wherein the commercial establishment is located within a user-selected promotional range. A number of mobile devices connected to either common or different local networks may also communicate to one another (via chat, voice or video chat, send images, data, etc.) so long as the mobile devices are disposed within a user-selected communication range.
