Ian Essling and Jason Clough of Comscore uncovered trends in U.S. digital commerce, which reached $1 trillion for the first time last year, a benchmark resulting from a buildup of year-round spending rather than mostly focused on the holiday season. Their data was comprised of two types, mobile (mobile or tablet) and digital (mobile or desktop) commerce. Each was defined as dollars spent online in non-travel, retail categories. Mobile now accounts for 40% of all digital retail dollars spent. Groceries, which includes pet supplies, health and beauty and baby supplies, saw record mobile and digital growth last year, overtaking apparel for the first time. In addition, while in the past, U.S. consumers were resistant to buying big ticket items, such as rugs, TVs, consumer electronics, a car or furniture, online, today such actions have become commonplace.
