Mark Zuckerberg

Facebook CEO Mark Zuckerberg, Time magazine's 2010 Person of the Year, is not the first honoree from the world of technology and science. He's in good company, with a list that includes tech titans, a machine, and even a planet.

Time cited Zuckerberg "for connecting more than half a billion people and mapping the social relations among them, for creating a new system of exchanging information and for changing how we live our lives."

Since 1927, Time magazine has chosen someone or something that, "for better or worse," made the greatest impact during the year. The story goes that Time editors first came up with the idea during a slow news week. (That sounds familiar.)

CNET has culled from the list to highlight winners in the technology and science fields.

We've also created a poll to discover our readers' pick for tech person of the year.
