Online Sales Jumped 16.5% on Christmas Day

It's been a good season to be an online retailer. Not only did online retailers get a head start on Thanksgiving Weekend sales, they were also able to get a jump on after-Christmas sales, posting some of their biggest discounts of the year in the early hours of Christmas Day. And shoppers (us included) took advantage: Sales on Christmas Day jumped 16.5 percent over last year - an even bigger percentage increase than what online retailers saw over Thanksgiving Weekend, according to IBM.
