Trending: Amazon and Seattle’s NBA dreams: Steve Ballmer on the city’s prospects for bringing back the Sonics


Cyber Monday is traditionally the day that office workers troll for deals at their desks when the boss isn’t looking, but numbers from IBM suggest that lots of people are now shopping on their phones on the bus into work.

U.S. online retail sales on Monday were 20.6 percent higher than on Cyber Monday last year — making yesterday the biggest online shopping day in history — and mobile devices represented 31.7 percent of all online traffic, according to numbers released this morning by the company’s Digital Analytics Benchmark service. IBM didn’t release sales numbers, but the trend is good news for and other online retailers.

Some interesting factoids from the report show a difference between people shopping with iOS and Android devices: IBM says iOS users spend $120.29 per order on average, and represent 14.5 percent of all online sales. Android users spend an average of $106.70 per order, and represent 2.6 percent of all online sales.

Smartphones drove more traffic, but tablets were responsible for more actual purchases — representing 11.7 percent of all online sales, compared with 5.5 percent for smartphones, according to the IBM report.
