A light bulb illuminates whenever someone walks beneath this billboard for The Economist, a popular political and international affairs publication. I like the eye-catching nature of this board: a passerby may glance over the ad then notice it light up and turn back to look again. The image of the light bulb also reflects The Economist’s aims “to take part in a severe contest between intelligence, which presses forward, and an unworthy, timid ignorance obstructing our progress.” (From The Economist website.)
Though the board contains no other text other than simply “The Economist” its message is extremely clear, making it an excellent blend of guerrilla marketing and traditional billboard advertising.
