Colleges try to leverage the social media savvy of their students with “social media ambassador” programs that help them advertise to prospective new students, raise the schools’ profiles, and educate their current students about school programs. And for some influencers, like Giannulli, college can be a windfall, landing them brand deals to market dorm furnishings, Victoria’s Secret underwear, and tooth-straightening solutions to their fellow students. For others, college just gets in the way of their real passion.
