In my diploma thesis, I will present a complex and long-lasting process of changing the entire corporate identity in an international company. The process involves many different experts from different fields. I will present selected tools for successful management of such an extensive project where I will devote special attention to the preparation of multimedia content. In my diploma thesis, I will pay special attention to the renovation of the website and social media. It is important that we look at the renovation as a whole, which comprises all communication channels, so I will also present a selection of printed matter. This is followed by an analysis of the renewal of the website of the selected company and a comparison with the competition.
