TIME Magazine has been naming a Person of the Year since 1927 and their choice always makes waves.
The honor is meant to highlight the person, people, or even thing that "for better or for worse... has done the most to influence the events of the year."
It's not about who (or what) is the best person of the year, but the one that has made the most waves. The person that defines a huge portion of the culture for that given year.
