Notes: US retail e-commerce purchases from desktop computers during November and December 2014 grew 15% year-over-year to reach $53.3 billion, slightly exceeding expectations after missing them last year. Cyber Monday was again the heaviest e-commerce day (in history), though it was Thanksgiving Day that sportedÂ the largest year-over-year gain (32%). Separately, IBM reports that overall online sales (including mobile) grew by 13.9%, with mobile accounting for 45% of traffic (up 25.5% year-over-year) and 22.6% of sales (up 27.2%). Key trends outlined earlier in the holiday season held true: smartphones outpaced tablets in traffic share, but lagged in sales share; average order values were higher on desktops ($125.12) than mobile devices ($104.82), and iOS topped Android in mobile device traffic share, sales share, and average order value.
