In addition to explaining basic terms such as expressing emotions, computer mediated communication, understanding of the context and emotions that are essential for understanding the research part of the work, this paper explains why the emphasis is placed on the context itself and how it affects the overall communication. It is precisely the context which laks in computer mediated communication, in which today emoticons are taking the lead and have an increasing importance in expressing emotions. In order to understand what is happening with them today, it is important to study their history and beginnings, but also to explain how emotions can be expressed by using them. Given the fact that the emphasis has been placed on expressing emotions in Internet communication in the business world, the paper further explains what are the features of business communication and whether emotions are generally welcome in that said type of communication. In this paper, we also conduct research into that shows how emotional expression works in practice, i.e. research will show if there has been a change in the communication in business situations. Thereby we have answered questions such as, whether emoticons are a substitute for mimics and gesture, are they used more in private or business communication, if the use of an emoticon differs based on the hierarchical position of the people and whether there is a misunderstanding of the message due to the lack of understanding of the emotion.
