What is the difference between e-Commerce and e-Business? Also in detail, why do some people say B2B (business-to-business) has greater potential than BSC (business to consumer)?

E-Business is any business process that relies on an automated information system. This is mostly done with Web-based technologies currently.

E-Business methods enable companies to link their internal and external data processing systems more efficiently and flexibly, to work more closely with suppliers and partners, and to better satisfy the needs and expectations of their customers.

E-Business includes e-Commerce.

E-Commerce consists of the:
- Distributing,
- Buying,
- Selling,
- Marketing, and
- Servicing of products or services over electronic systems such as the Internet and other computer networks.

E-Commerce is an electronic business application aimed at commercial transactions. It can involve electronic funds transfer, supply chain management, e-marketing, online marketing, online transaction processing, electronic data interchange, automated inventory management systems, and automated data collection systems. It typically uses electronic communications technology such as the Internet, extranets, e-mail, e-books, databases, catalogues and mobile phones.

B2C is Business-to-Consumer Market which means businesses sell products and services to consumers for household or personal use
B2B is Business-to-Business Market which means businesses sell products and services to other businesses for use in their daily operations or for making other products and services

Sectors of the B2B Market:
* Producers - includes all manufacturers and service providers; buy goods to use in making other goods or services
* Middlemen - buy goods for resale; includes all retailers and wholesalers (distributors, vendors)
* Government - includes all federal, state, and local governments and govt. agencies
* Nonprofit - includes charities, schools and universities, museums, etc.

Published articles [1] indicate that the B2B market is five times as large as the B2C market in the USA. That is why some people say B2B has greater potential than B2C.
