NEW YORK (CNNMoney.com) -- Online sales on Cyber Monday surged nearly 20% from last year, according to findings from an analytics group released Tuesday.
Cyber Monday is the first Monday after Thanksgiving and is a relatively recent retail phenomenon, compared to Black Friday, the day after Thanksgiving. Many retailers traditionally open their doors at midnight on Black Friday, attracting shoppers with heavily advertised discounts.
Cyber Monday online sales in the U.S. were up 19.4% in 2010 compared to last year, reported Coremetrics.
More people were shopping online and the individual orders were larger than last year. Coremetrics said the average order value on Cyber Monday was $194.89, an increase of 8.3% from last year's average of $180.03.
Cyber Monday sales also outdid this year's Black Friday online sales by 31.1%, according to Coremetrics.
Shoppers also used mobile devices to make their purchases, with nearly 4% of all Cyber Monday shoppers using smartphones and other devices.
Mobile phones play a key role. "People are using their mobile phones to compare prices, look for store locations and inventory in stock locally and find deals," read the Google blog.
