Dive Brief:

• E-commerce sales will likely be 11% of retail sales, soaring to $414 billion by 2018 from the $263 billion in 2013, according to a new study by Forrester Research. 

• Millennials, especially those 25 to 33 years old who are reaching their peak spending years, are continuing to move the numbers in e-commerce. 

• The research firm also says m-commerce will increase 33% each year through 2017, and will continue to have an intense impact on sales in physical stores.

Dive Insight:

Beyond the numbers in this report is the clear message, once again, that mobile-and-web commerce is becoming tightly knit with brick-and-mortar commerce. Certainly consumers, especially younger ones who have grown up with the web and mobile as accepted portals to all aspects of their lives, expect most retailers to provide seamless opportunities on devices and on the street.
