I believe that marketing is one of the most important tools of business development because this helps to meet the market, find the customers and acquaint companies with people. That is why I evaluate the importance of marketing strategy inside corporate strategy focusing on event marketing and Corporate Social Responsibility. In my thesis the effect of event marketing on consumers' perception and on corporate image was analysed, just like the further effects of these events if their message connects to Corporate Social Responsibility. It is also interesting how these things associates to corporate strategy. I wanted to confirm that a well-prepared and carefully planned event marketing with a positive message can invigorate the interest of managers, owners and buyers, consumers and can build the corporate image, which proves that marketing communication is an essential part of corporate strategy. In my opinion the topic is very current, because in today's world - where marketing communication tools are going through continuous innovation and development, which affects to the communication of companies as well - it is necessary to convey the right message and to be creative in addressing the consumers in order to stay competitive.
