NEW YORK (TheStreet) -- Cyber Monday online sales set a new record of $2.29 billion, up 16% from 2012, according to the Adobe Digital Index 2013.
About 18.3% of the sales were from consumers using mobile devices, an increase of 80% from last year, Adobe said.
The record breaking online sales Monday were in addition to record-breaking Internet sales on Thanksgiving Day and Black Friday, at $1.06 billion and $1.93 billion, respectively, according to Adobe data.
Total online sales from Thanksgiving through Cyber Monday surged 26% to $7.4 billion. While so-called "brick-and-click" retailers dominated the Thanksgiving weekend sales, Internet retailers, namely Amazon
(AMZN - Get Report) and eBay
(EBAY - Get Report), generated the most sales on Cyber Monday, with a 42% share.
Wal-Mart (WMT) said on Tuesday that its Web site had its best sales day ever on Cyber Monday though it didn't release specific sales numbers. Walmart.com processed more than 1 billion page views between Thanksgiving and Cyber Monday, the Bentonville, Ark.-based retailer said.
Top-selling items on Walmart.com on Cyber Monday included: an LG 50" LED HDTV and the Apple (AAPL) iPad 2 16GB with Wi-Fi.
Cyber Monday consumers shopping on their smartphones or tablets generated $419 million of sales yesterday, with tablets driving more of the mobile sales than phones, Adobe says. Social media also contributed on Monday. Facebook (FB) brought in two-thirds of the $148 million in social media-driven sales over the weekend (up 12% from last year), while Twitter's (TWTR) share rose to 9% (that's an increase of 24% year over year). Pinterest also saw strong growth increasing its share of referral traffic by 17% year over year, Adobe says. "Retailers earned 10% of their annual sales in just the last five days, an increase of 26% (year over year)," said Tamara Gaffney, Adobe's principal analyst. "Sales from mobile devices saw the biggest gains with an 80% increase over last year."
ShopperTrak estimates that bricks-and-mortar retail sales over the four-day weekend rose just 1% as shoppers spent an estimated total of $22.2 billion. Retail shopper traffic decreased by 4%, to an estimated 1.8 billion store visits, the analytics firm said Tuesday. While total in-store shopper traffic rose by 9.4% in the apparel sector, store traffic in the electronics sector decreased by 6.5% for that same time period, ShopperTrak says.
The National Retail Federation estimates that consumers, on average, spent 4% less than they did last year, on Thanksgiving weekend thanks to strong promotions and sales by retailers. The NRF estimated that shoppers, on average, spent $407.02 compared to $423.55 last year. Total spending for the four days is expected to reach $57.4 billion. The NRF still expects holiday spending to rise 3.9% to $602 billion. Adobe's online shopping data is based on the analysis of nearly 900 million visits to 2,000 retailers' Web sites on Cyber Monday and more than 3 billion visits since Thanksgiving Day. -- Written by Laurie Kulikowski in New York.
