Probably some of the most famous advertising in the world (certainly up there with Times Square) are the wall of lights in Piccadilly Circus. Vary over time in number, advertisers, and type the lights date back to the beginning of the 20th Century. they occupy a building owned by Land Securities; and now even have their own website!
Although most impressive after dark I find that they have a certain charm at dawn as London comes alive.
