National culture is a set of specific behaviors of an individual, that are accepted, intergenerational, transferred through symbols and are characteristic for certain groups of people. It consists of three groups of phenomena: 1. patterns of behavior, 2. common values, beliefs and rules and 3. tools and techniques (technology). There are various classifications of cultures and this thesis covers the most accepted ones (Hofstede, GLOBE, Trompenaars). Global cultureis a recent term that presents creating a common culture for people all over the world. The main causes for creating this new global culture are: widespread use of English, spreading information easier than ever (cyberculture) and consumerism. The thesis gives a detailed explanation of each of the causes and it also predicts possible future developments of cultural globalization.
