A new report says more "Cyber Monday" shoppers than ever made purchases online, driving up sales 33 percent.
According to IBM Benchmark, those shoppers spent an average of $193 per order. About 80 percent of online retailers offered special "Cyber Monday" deals.
Web traffic rose 28 percent on Monday, according to another firm, online content-delivery firm Akamai. The peak was at 6 p.m. PT when shoppers on both the East and West coasts were online.
Meanwhile, more people are using their mobile devices to shop online. Usage of smartphones and tablets jumped from about 2 percent last year to about 6.6 percent this year.
The numbers echo a strong shopper showing in stores over the holiday weekend. A record 226 million shoppers visited stores and websites during the four-day holiday weekend starting on Thanksgiving Day, up from 212 million last year, according to The National Retail Federation.
The term Cyber Monday was coined in 2005 by the NRF, a retail trade group, to encourage Americans to shop online.
