The New Yorker:

Data excite advertisers. Prowling his London office in jeans, Keith Weed, who oversees marketing and communications for Unilever, one of the world’s largest advertisers, described how mobile phones have elevated data as a marketing tool. “When I started in marketing, we were using secondhand data which was three months old,” he said. “Now with the good old mobile, I have individualized data on people. You don’t need to know their names . . . You know their telephone number. You know where they live, because it’s the same location as their PC.”

Weed knows what times of the day you usually browse, watch videos, answer e-mail, travel to the office—and what travel routes you take. “From your mobile, I know whether you stay in four-star or two-star hotels, whether you go to train stations or airports. I use these insights along with what you’re browsing on your PC. I know whether you’re interested in horses or holidays in the Caribbean.”

By using programmatic computers to buy ads targeting these individuals, he says, Unilever can “create a hundred thousand permutations of the same ad,” as they recently did with a thirty-second TV ad for Axe toiletries aimed at young men in Brazil. The more Keith Weed knows about a consumer, the better he can aim to target a sale.

It feels as if we are at a real inflection point. We can go down the path of allowing marketers unfettered access to all the data they can possible vacuum up about us, giving up privacy in favor of “better” advertisements, or we can try, using any number of personal, governmental and software/hardware-based solutions as we can develop, to lock them out of our lives.
