E-commerce involves the buying and selling of goods and services over the internet. It began in the 1960s with businesses sharing documents electronically. In the 1990s, the rise of eBay and Amazon revolutionized e-commerce by allowing consumers to purchase items online. There are four main categories of e-commerce: business to business, business to consumer, consumer to business, and consumer to consumer. Common applications of e-commerce include supply chain management, online payments, e-commerce platforms, and social media. The advantages of e-commerce include overcoming geographical limitations, 24/7 access, gaining new customers, and easier business management. However, disadvantages include uncertainty over product quality and the potential for technical failures or fraudulent sites

started using Electronic Data Interchange (EDI) to share business documents
with other companies.
*In 1979, the American National Standards Institute developed ASC X12 as a
universal standard for businesses to share documents through electronic
networks.
After the number of individual users sharing electronic documents with each
other grew in the 1980s, in the 1990s the rise of eBay
and Amazon revolutionized the e-commerce industry. Consumers can now
purchase endless amounts of items online, both from typical brick and mortar
