An anonymous reader quotes CNN Money: Black Friday 2017 was all about digital sales. American shoppers spent a record $5 billion in 24 hours. That marks a 16.9% increase in dollars spent online compared with Black Friday 2016, according to data from Adobe Digital Insights, which tracks 80% of online spending at America's 100 largest retail websites... Meanwhile, malls and big-box retailers were left only slightly emptier. Early estimates from ShopperTrak, a data analytics company that measures the number of shoppers at stores, said foot traffic "decreased less than one percent when compared to Black Friday 2016."
