A lighter-than-air balloon (17) is illuminated from within by an internal light source (18). This light source (18) may be energized by a power source carried on-board the balloon when aloft, or from a ground based power source (32) tethered to the balloon (17) by a conductor (30) connected to the light source (18). Spectators attending an event, usually a festive occasion, may use a switch 36) on ground to switch on and off the light source (18) aloft in the balloon (17). By displaying on an internally illuminated balloon (17) while aloft indicia (17b) of the subject being advertised, a very creative and effective advertisement is broadcaster over a wide geographically area potentially reaching millions of onlookers.
