The 1990th of the last century brought big changes, firstly by the powerful penetration of information and communication technology. This trend has exerted influences on the development and application of marketing in both theory and practice. Thanks to the development and implementation of CRM systems, companies have had insight into the complete behavior of their customers, even in the situations where companies have a great number of different customers.
