Final answer:
The question asks about the growth of retail e-commerce in the US for 2014-2015, suggesting a positive trend. Economic indicators such as lowered unemployment rates and a 4.6% GDP growth signal a favorable environment for eCommerce growth. Increased ad spending in the mobile sector also likely encouraged this growth.
Step-by-step explanation:
The question pertains to the expectation of retail e-commerce growth in the United States during the years 2014-2015. While specific growth rates for this period are not provided in the information given, we can infer from the context that the retail e-commerce sector might indeed experience a positive trend. Contributing factors to the overall economic optimism include lowered unemployment rates, an increase in the Gross Domestic Product (GDP) by 4.6% in the second quarter of 2014, a rise in housing valuation, and a revitalized stock market, as noted by the US Department of Commerce-Bureau of Economic Analysis and other economic reports.
Additionally, data from eMarketer.com in 2014 indicated that total US ad spending was expected to see the largest increase since 2004, with mobile advertising leading growth and set to surpass traditional forms of advertising such as radio, magazines, and newspapers. This surge in ad spending, particularly in digital and mobile sectors, may have likely contributed to stimulating retail e-commerce growth.
