High tech video billboards are multiplying in city spaces across the world, woven into the fabric of everyday life, from ribbon videos down escalators on the London underground, to French metro corridors, New York taxis, bus-shelters, newspaper kiosks, and – increasingly – broadcast from shop windows onto the street. They are becoming more sophisticated and interactive, with the potential to collect data from passersby; increasingly bright and inescapable – impossible to click off or block like you can online. But in France, there is fresh debate on how urban planners and local councils should limit them in the public space for the sake of our overloaded eyes and brains. – The Guardian
