Online shopping emerged with the development of the internet in the late 20th century. Entrepreneurs saw the potential for online shopping and created virtual storefronts, allowing consumers to shop without leaving home. Early examples of online shopping included businesses connecting via electronic data interchange in the 1960s and a UK grocery delivery service starting in 1979. Online shopping became widely popular after 2000 as more consumers shopped online and websites like Amazon, Flipkart, eBay, and Snapdeal established large online marketplaces.
