Current generations (Y, Z, Me...) are known as the Silent Generation because they make extensive use of mechanisms of social media and messaging (SMS and more recently Whatsapp) rather than voice services. Such generations, which begin to be responsible for much of the consumer market, feel more comfortable with the message exchange instead of direct relations that normally occur in services commercialization and post-sales support, facilitating the expansion self-service solutions for this public. In this perspective, it is interesting to understand how these new consumers behave in social media and the relationships and issues that lead them to adopt new technologies and consume new products and services that can bring significant implications for the evolution of both academic theory and for managers. In the present study we propose a conceptual model to evaluate the intention to adopt a new technology, integrating the social relations of endorsement to the modulatory effects that social media Narcissism (Narcissism in social media) may have on the affective dimension since consumption itself is not an end but rather a means to assert themselves. Online surveys with mobile phone service consumers were analyzed through structures equation modeling in order to test if the hypotheses created by evidence of the relationships observed in the literature review were confirmed or not.
