E-commerce refers to the buying and selling of goods and services using the internet. The first online sale occurred in 1994 when a CD was sold from an individual's website. Global e-commerce sales are projected to reach $27 trillion by 2020. E-commerce provides benefits to businesses like reducing costs and reaching more customers, benefits customers with convenience and choice, and benefits society by connecting people and facilitating public services. However, e-commerce also lacks personal interaction, depends on internet connectivity, and prevents experiencing products before purchase.
