Who were the women who changed the world in the first decade of 2000? They were women who dominated technology, media and politics -- three areas in which female trailblazers spearheaded new projects, put forth bold ideas, and stepped into jobs that had never been held by women before -- and in some cases, had never even existed before. Some names and faces you'll recognize. Others may prompt you to ask, "Who?" But all have one thing in common: they changed the world as we know it in the years 2000-2009, and what they did shaped and defined the first decade of the 21st century.
