Today, Millennials make up about 25% of American workers, according to the U.S. Bureau of Labor Statistics. By 2020, that number will grow to more than 40%. If you would want that high amount of growth for your income stream, then you should target the millennial generation. No one will understand millennials better than someone who belongs to the group.
Another reason is, its "digital" marketing - modernized and in need of fresh ideas. Millennials have a proven track record in innovation. Facebook's Zuckerberg is a millennial. Most tech startup founders and team members are millennials. They really break traditions and creating the new way of living. Digital marketing is far from the old school marketing. Like, if you would turn back the time where internet still does not exist, then present the idea of content marketing - which means providing informative cues rather than salestalk, most probably it will be labelled as absurd.
Why Millennials Should Do Your Digital Marketing?
