Billboards That Look Back

In advertising these days, the brass ring goes to those who can measure everything — how many people see a particular advertisement, when they see it, who they are. All of that is easy on the Internet, and getting easier in television and print. Billboards are a different story. For the most part, they are still a relic of old-world media, and the best guesses about viewership numbers come from foot traffic counts or highway reports, neither of which guarantees that the people passing by were really looking at the billboard, or that they were the ones sought out. Now, some entrepreneurs have introduced technology to solve that problem. They are equipping billboards with tiny cameras that gather details about passers-by — their gender, approximate age and how long they looked at the billboard. These details are transmitted to a central database. Behind the technology are small start-ups that say they are not storing actual images of the passers-by, so privacy should not be a concern. The cameras, they say, use software to determine that a person is standing in front of a billboard, then analyze facial features (like cheekbone height and the distance between the nose and the chin) to judge the person’s gender and age. So far the companies are not using race as a parameter, but they say that they can and will soon. The goal, these companies say, is to tailor a digital display to the person standing in front of it — to show one advertisement to a middle-aged white woman, for example, and a different one to a teenage Asian boy. “Everything we do is completely anonymous,” said Paolo Prandoni, the founder and chief scientific officer of Quividi, a two-year-old company based in Paris that is gearing up billboards in the United States and abroad. Quividi and its competitors use small digital billboards, which tend to play short videos as advertisements, to reach certain audiences. Over Memorial Day weekend, a Quividi camera was installed on a billboard on Eighth Avenue near Columbus Circle in Manhattan that was playing a trailer for “The Andromeda Strain,” a mini-series on the cable channel A&E. “I didn’t see that at all, to be honest,” said Sam Cocks, a 26-year-old lawyer, when the camera was pointed out to him by a reporter. “That’s disturbing. I would say it’s arguably an invasion of one’s privacy.” Meanwhile, privacy concerns about cameras are growing. In Britain, which has an estimated 4.2 million closed-circuit television cameras — one for every 14 people — the matter has become a hot political issue, with some legislators proposing tight restrictions on the use and distribution of the footage. Reactions to the A&E billboard in Manhattan were mixed. “I don’t want to be in the marketing,” said Antwann Thomas, 17, a high school junior, after being told about the camera. “I guess it’s kind of creepy. I wouldn’t feel safe looking at it.” But other passers-by shrugged. “Someone down the street can watch you looking at it — why not a camera?” asked Nathan Lichon, 25, a Navy officer. Walter Peters, 39, a truck driver for a dairy, said: “You could be recorded on the street, you could be recorded in a drugstore, whatever. It doesn’t matter to me. There’s cameras everywhere.”
