Tablets, Smartphones Drive Mobile Commerce to Record Heights

Maybe 2012 was the year of mobile after all. U.S. retail m-commerce sales shot up 81 percent to nearly $25 billion last year, propelled by rapid adoption of tablets and smartphones as shopping devices, according to new estimates from eMarketer. Mobile devices accounted for 11 percent of total U.S. retail e-commerce sales in 2012, eMarketer estimates, and further growth is expected to push mobile sales to a 15 percent share of all U.S. retail e-commerce sales this year.
