Mark Zuckerberg
Millions all over the world recognized Mark Zuckerberg as the brains behind Facebook. The Harvard University dropout created the wildly popular social networking site from his college dorm room in 2004 and witnessed its exponential growth over a short period of time. Its interactivity and user-friendly platform allowed Zuckerberg's site to expand beyond the social networking realm and evolve into a marketing tool and entertainment hub. In less than a decade, Facebook's meteoric rise expanded into launching grassroots campaigns, raising sociopolitical awareness, and establishing Zuckerberg as one of the most influential visionaries of his generation.
