The fight for consumers’ eyes—and wallets—is only getting fiercer. Recently, New York City’s Metropolitan Transit Authority announced it would begin selling ad space on the front of subway fare cards to offset rising costs. Starting this October, for as little as $350,000, companies get creative control over everything but the magnetic stripe on 1 million cards—not such a bad deal, considering those cards will be in the hands of 8.5 million daily subway riders.
