This is the final work of the Marketing Management course, which covers the topic of consumer attitudes in the context of generations and media that advertise various products and services. The specific media that I will focus on the most are television and social networks, the first two completely different media that do not challenge each other and do not suit the roles of competitiveness. However, both are very dominant advertising tools that have marked generations and especially the generation to which myself belong. Of course, this is about Generation Y, known to many under the pseudonym "millennials". The main position taken in writing this paper was the one from the psychological point of view of the nature of human behavior. More precisely, the behavior and attitude of the average millennial in their lifetime so far has been greatly influenced by advertising, in the more traditional way television and more recently, digital. The paper is based on the thesis that the current Generation Y was raised and prepared in the environment of the television boom as an overture to the technological explosion in which the marriage between the Internet and smartphones flourished. This environment is extremely potent for the sale, ie advertising of products and services that have flooded the relatively cheap advertising space compared to television. Of course, the point and meaning is not in cheaper advertising, but in efficiency. There are, on average, cheaper advertising options like the radio one, but with several times less efficiency, which puts it far behind social networks in terms of cost-effectiveness. Prices and conditions change from day to day, which, according to the current situation on the market, imposes social networks as the most attractive medium or form of advertising. The aim of this paper is to conclude how and why this happened and what is the attitude of the "key" generation in relation to television, given that they are both responsible for the position in which social networks are today.
