"For the last eight years Los Angeles has been engaged in a war with the outdoor advertising industry."
"As the lawsuits pass back and forth, the technology of outdoor advertising evolves, presenting new visual challenges for communities and endless opportunities for commercially bent designers. Giant whole-building vinyl supergraphic wraps, obscure skyscrapers and warehouses. One company with its roots in Los Angeles, SkyTag, claims their supergraphic wraps are so big they can be seen from space. Yet giant wraps and digital billboards that change messages every four to six seconds distract drivers, ramp up danger of vehicular collisions at intersections, obscure views and provide undesired night lighting in the bedrooms of residences hundreds of feet away. In the very near future, LED arrays mounted in the window walls of buildings will turn night skies into pulsing fields of light pollution. The stuff of science fiction less then a decade ago, holographic and "smart" billboards already tailor their messages to passing motorists and pedestrians using blue tooth and wireless technologies interacting with mobile phones and personal digital devices. The cacophony of existing and potential environmental information delivery can be exhilarating, if you are in the right mood; but more frequently it's exhausting and contributes to green house gas emissions (especially if you think about all that energy being used to power the digital signs). In Los Angeles, which has lost control of its visual environment, more and more people experience the presence of these extra-enabled billboards as an assault, yet another sign of private interests trumping the public good. In this Babylonic Empire of signs what little sense of the natural that is left, is pretty much diminished by the commercialization of every inch of urban space."
