The domestic three, Toyota Motor Corp., Nissan Group and Honda Motor Co. all reported double-digit gains. The seasonally adjusted annual sales rate surged to 18.17 million, easily topping the 17.7 million forecast.

Also 17% of the millennials named Google as their most trusted tech brand, followed by Apple (12%).

The survey also showed that millennials are more likely to be brand loyal than older consumers.

Carole Little, a Los Angeles fashion designer whose sportswear found an eager audience among working women looking for affordable style, died on Sept. 19 at her home in San Diego. She was 80.

Martin Sorrell says this behavior puts big pressure on his holding company WPP, the incumbent on several accounts. "[Are the reviews] because of transparency, a rebate issue in a non-rebate market, because of a lack of trust, media fragmentation, or because media is the biggest line item in PNLs?"

Tesla CEO Elon Musk launched the Model X SUV at an event this week, but it wasn't exactly rocket science. Maybe it should have been. First, Musk is a rock star, but not the kind that can get away with delaying the start time by two hours. But then the gorgeous car comes out, and instead of focusing on how the electric crossover with gull-wing doors even is the quintessence of beauty, design, and technical wizardry, he spends ten minutes talking about how safe it is in case you crash.
