E-Commerce
With the advent of the Internet, marketing goods and services have been transformed from discrete location-based and remote pricing strategies to global, always-on, price-sensitive, and possibly multilingual vehicles for delivering those goods and services to customers.
Amazon.com proved that there was a worldwide market for everything from 
books and music to clothing and appliances, and Amazon is rewriting the rules for how to effectively reach and satisfy a customer base that is potentially anywhere in the world. With this worldwide sales potential comes the equally mammoth task of determining how to effectively market to and support such a potentially huge and diverse customer base.
And retail as a "standard" mode of doing business? You can forget that old notion forever. Take a look at eBay's revenue numbers and enormous category list of offered products to prove that e-commerce in "non-standard" formats is here to stay. However, along with that large market potential come equally huge support tasks and legal implications. Taking the time and effort to develop a comprehensive online marketing strategy is necessary for any organization attempting to tap this new worldwide market.
