Markets are places where buying and selling of goods and services takes place. In recent times, with the advent of technology, markets have changed drastically. Now, the buyers and sellers do not have to go to shops for buying and selling. Through the use of the Internet, buying and selling can be done online. Payments can be made via credit cards and Internet banking. Examples of such e-commerce initiatives are Amazon.com, flipkart.com, ebay.com, etc.
Use of smart phones to place orders is further eliminating the need to physically visit the shops. Sometimes, the agents of the company can visit the homes of the consumers directly to sell their goods. Medical representatives who visit doctors to demonstrate a sample of their medicines is one such example. Thus, we can say that buying and selling does not necessarily have to take place by visit the shops; there are other means of trading as well, such as the Internet, phones and door-to-door selling.
