This years Amazon Prime Day smashed its single-day sales record from a year ago, sending the clear message that online shopping is tracking to become the main method of retail commerce.

Prime Day is when shoppers with Amazon Prime memberships can take advantage of special sales offered by the pioneering online retailer. First launched in 2015 for the company's 20th anniversary, it was brought back this year on July 12. said Prime Day is more than an anniversary. It's an event that Amazon uses to remind its competition in physical retail and e-commerce of its dominance in a fast-changing industry.

In 2015, Amazon accounted for 60 percent of all U.S. online sales growth, according to Other factors expected to drive up e-commerce sales outside of Amazon's popularity include a stronger economy, retailers gaining repeat customers and a desire to wed offline and online retail to "maximize efficiency," with U.S. online sales set to pass the $530 billion mark by 2020, it continued.

"If it weren't for Prime, Amazon might have been just the name of a river," writes Ben Fox Rubin for, along with calling it "the king of e-commerce." Since it's launch in 2005, The Prime service has inspired its rivals Walmart and eBay to try similar membership programs, he added.

But it's difficult to compete with Amazon's locked-in customer base. While other retailers such as Walmart and J.C. Penney launched their own sales and free shipping to compete with Prime Day, "theres a massive difference between playing in Amazons sandbox and kicking dirt in its face," writes Jason Ankeny for RetailDIVE.

"Amazon alone has all the pieces in place to make an event like Prime Day work," Ankey wrote.
