Internet sales jumped more than 30 percent on Cyber Monday, making it the biggest online shopping day ever, according to data released on Tuesday.
Walmart.com, the online division of Walmart U.S., had its best sales day in history, a spokeswoman said.
Cyber Monday also was a record day for sales of Amazon.com's Kindle devices, the online retailer said, without specifying the number sold.
Still, eBay, operator of one of the largest online marketplaces, outperformed its arch rival Amazon.com over the crucial first five days of the holiday shopping season, according to one closely watched measure.
Research company comScore had forecasted that Cyber Monday sales this year would top $1.5 billion.
Cyber Monday has been the biggest online shopping day in recent years, as workers return to offices and make holiday purchases on their computers. This year, the boom in smartphone and tablet adoption has added extra fuel to online shopping.
