In a new report, "E-Commerce in the US: Retail Trends," eMarketer reviews changes over the decade since the first online purchase and looks to the future of e-commerce. A full decade old, e-commerce accounts for a $140 billion in business, and online shoppers now closely resemble the U.S. population as a whole. According to Forrester, between 2003 and 2004, the average online shopper became a year younger, was more likely to be female, less highly educated, with slightly lower household income, and increasingly accessed the Internet through a broadband connection.
