The current paper presents an analysis of the concept of advertising and its functions in the present-day world. Three prime advertising functions have been singled out: the informative or communicative, economic and social. In addition, the impact of advertising on the consumer is discussed based on seven main appeals (fear, humour, sex, music, rationality, emotions, scarcity) used by advertisers when targeting feelings and emotions of an audience. Moreover, the paper presents and defines the concept of shocking advertising as well as analyses the aims of its use. One of the main purposes of shocking advertising is to draw the attention of the target audience to the advertising message. It is rather frequent that shocking content -disgusting images, sexual reference, profanity/ obscenity, vulgarity, impropriety, moral offensiveness and religious taboos -is presented and described.
