The internet was born on New Year’s Day, 1983, when ARPANET deployed TCP/IP as the communications protocol for distributed computing.

It’s a pretty fair bet that the first online sale was consummated by Valentine’s Day, just six weeks later.

It wasn’t until the installed base of smartphones hit critical mass, however, that the eCommerce industry truly exploded. The unprecedented rise of mobile devices worldwide has disrupted the shopping habits of an entire civilization. The smartphone’s convenience, speed, and ease of access have proved irresistible to consumers around the globe.

eCommerce statistics reveal a confluence of retailer push and consumer pull. Online buying and selling is rapidly becoming the new standard in consumer shopping. Volume - whether measured in transactions or dollars - has attracted increasingly serious and powerful competition for online retailers. And it has opened the door to unprecedented innovation. 

This page summarizes Fortunly’s research into the current state and promising future of eCommerce.

(Think with Google)

U.S. online grocery shopping is strangely lagging behind other economies and eCommerce markets like the U.K. and South Korea, where customers already buy over 10% of their groceries online. Only 2% of groceries in the United States are purchased online, but the market is set for a huge expansion, especially now that Amazon has bought Whole Foods.

Internet user penetration level in the US is projected to be 88.7% in 2020.


As consumers get more connected, penetration levels for eCommerce marketing continue to rise. In fact, projections indicate that the internet penetration rate might rise by 5% in the next three years, reaching 93.7% by 2023. This will bode well for online shopping retailers big and small alike.

Final Words

Online shopping is more than an emerging industry. It is already one of the most important ways for large and small business to reach customers. If eCommerce market-size projections are to be believed, digital shopping will only continue to grow more important. Technical innovations like drone-based delivery systems and autonomous vehicles will accelerate the trend.

Consumers are pushing both the smallest and the biggest online retailers to offer better service and more generous offers. Today’s customer has more power than any in history, and the power is growing as the number of online shoppers increases.

If the eCommerce statistics we compiled here indicate one thing, it’s that consumer satisfaction is what makes or breaks any online business, no matter how big or small.
