The big winner of the holiday season so far: mobile shopping

For the first time ever, smartphones and tablets accounted for the majority of all online traffic on Thanksgiving Day, according to data analysis by IBM. On Black Friday, one in four online purchases were made on a mobile device. "The consumer expects to be able to go in and out of a physical and digital world in a completely seamless way," said Doug Hope, a retail marketing expert with GlobalShop. "This is the very beginning of a very significant shift in focus."
