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) and eBay (EBAY), 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.
Walmart.com will offer 200 online specials every day through Friday, Dec. 6. The company is also offering free shipping throughout the holiday season on all orders of $35 or more. Online orders can also be shipped to local Wal-Mart stores and in many instances, be picked up as early as the same day.
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.
