What recession? U.S. shoppers were out in force over the Thanksgiving weekend, spending a record $52.4 billion and getting the holiday shopping season off to an unexpectedly strong start. That’s raised hopes among online retailers that the trend will continue through today, Cyber-Monday, a made-up phenomenon that has nonetheless been more or less officially adopted by e-commerce sites as the focus of Black Friday-like promotions and discounts. Analysts estimate cyber-sales could reach $1.2 billion today, topping last year’s $1. 0 billion, while mobile e-commerce sales could double. Don’t expect much work to get done today, however. Roughly half of today’s online shopping is expected to be done while at work.
