8.Cyber Monday: By the Numbers Thanks to the growth of smartphones and tablets, which allow for “anytime, anywhere” shopping, eBay Inc. saw a surge in mobile commerce this past Cyber Monday across all divisions. On a year-over-year basis, mobile transacted volume more than doubled in the U.S. for eBay Marketplaces and nearly tripled for PayPal on a global basis. In addition, GSI saw a 287% increase in mobile sales in the U.S ., compared to 2011. PayPal research also noted that consumers around the world shopped on mobile most frequently from 1:00 p.m. to 2:00 p.m., PST, on Cyber Monday — slightly later in the day than on Thanksgiving and Black Friday .
