We, with the help of E-Commerce enables a firm or individual to conduct business over an electronic network, typically the internet. Electronic commerce operates in all four of the major market segments: business to business, business to consumers, consumer to consumer, and consumer to business. It can be thought of as a more advanced form of mail-order purchasing through a catalog. Almost any product or service can be offered via ecommerce, from books and music to financial services and plane tickets.
It allows firms to establish a market presence, or to enhance an existing market position, by providing a cheaper and more efficient distribution chain for their products or services. One example of a firm that has successfully used e-commerce is Target. This mass retailer not only has physical stores, but also has an online store where the customer can buy everything from clothes to coffee makers to action figures.
