This honors thesis study aimed to gain a better understanding of millennials and how to effectively use interactive marketing to advertise to this generation. The thesis was broken up into three segments. The first segment includes a literature review on: identifying and comparing within the millennial generation, millennials impacts on marketing, and an introduction to interactive marketing. The second segment covered the methodology study including the application of the research findings to analyze the effectiveness of interactive marketing and the shift brands have made to reach millennials. Lastly, the final section covered an overall conclusion and recommendations. This paper first identified who the millennial generation is and discussed the differences between the older and younger millennials among the generation as a whole. Then the paper moved into defining what interactive marketing is and how it is being used and targeted towards the millennial generation. The next section identified the key differences within the millennial generation and the main areas in which this generation impacted brands and the company's interactive marketing efforts. The research suggests what the most influential take-a-ways from the millennial generation are and how brands shifted in order to better target the new types of consumers. Additionally, the information obtained from understanding the millennials' perspective on interactive marketing provide companies a better idea of how to market to them. Lastly, the recommendation checklist for companies to follow on how to create a successful interactive marketing advertising campaign helped to position brands in the most efficient way possible when entering this new form of marketing and specifically targeting millennials.
