The harms of advertising are aptly attested by the Lucky Strike campaign of the late 1920s and '30s. The massive amounts spent on cigarette advertising had spurred demand for a dangerous product and deterred switching between brands, while also preventing cheaper newcomers from making much headway. The result was an oligopoly of branded cigarettes—Camels, Lucky Strike, and so on—that has lasted for decades, and, of course, no few cancerous lungs.
