According to research firm eMarketer, online retailers’ sales have hit the $1 trillion mark, a first time ever achievement. The $1 trillion mark is just the first of many ten digit years, as eMarketer projects 2013 ecommerce sales to reach $1.3 trillion. It also predicts the U.S. will no longer hold the number one position in terms of markets, as the Asia market is looking to surpass us this year. [Source: eMarketer]
