Facebook is developing ways to let companies use real-time location data to target consumers with mobile ads. After Facebook’s May IPO, shares fell as much as 32 percent in part because of investor concerns that the social network’s mobile ad revenue wasn’t keeping up with the growing number of users who access Facebook via smartphones. Facebook has been testing new ad products and showed almost a dozen ideas to corporate chief marketing officers and agency executives. While it’s also testing mobile “offers” that let retailers give coupons to customers who are nearby, Facebook trails Google, which takes in half of all mobile ad sales.

Drugmakers don’t have to pay sales representatives overtime, the U.S. Supreme Court ruled in a 5-to-4 decision that will save the industry billions of dollars. The court said drug reps are exempt from a federal wage-and-hour law because they are considered “outside salesmen” even though they don’t specifically take orders from doctors. GlaxoSmithKline, which was sued by two employees, had argued that representatives are salespeople because they’re trained to get commitments from doctors to prescribe drugs.
