Never before has the business environment of companies changed so quickly. People, industries and nations are increasingly interconnected. This trend is driven by the Internet. Every corporation needs to be aware of what impact the Internet has on its business environment as well as to understand which benefits it offers them. For this purpose companies first have to comprehensively understand how the medium of the Internet generally works and how it affects entrepreneurial activity. Afterwards, one has to recognize that processes on the web work differently than in traditional business. They are faster, more efficient and partly function in opposite directions compared to classical procedures. Even within the business processes of the Internet, there are fundamental differences between B2B and B2C approaches. Companies need to recognize their current positioning on the Internet, understand how business partners act over the Internet and identify appropriate information and transaction channels. Thus, to let your business prosper, it is time for a new twist to existing business - with E-Marketing.
