Online sales in the US on Thanksgiving Day 2013 exceeded $1 billion

"Thanksgiving became a billion-dollar online shopping day for the first time this year as more consumers used tablets to browse for deals from their couches and e-commerce companies ramped up promotions.
Thanksgiving online sales came in at $1.06 billion in the U.S., according to Adobe Systems, which analyzed 180 million visits to more than 1,000 U.S. retail websites.
Thanksgiving Day revenue for leading online retailers rose nearly 40% from last year, e-commerce firm Monetate said in a separate sales report. The totals reflected this year's rare convergence of the holiday with the first night of Hannukah.
The increases included a 73.6% rise in revenue from shoppers using tablets, a 50.7% rise in sales to smartphone users and a 39.8% increase in revenues via laptop and desktop computers, said Pennsylvania-based Monetate, which based the findings on data from nearly 30 million online shopping sessions."
