The presidential inauguration is a uniquely American ceremony that began over 200 years ago. "Every president since George Washington has given an inaugural speech to express his vision for the country, and they often contain some of the most powerful words, which we remember even to this day," CNN's Anderson Cooper says. "After the swearing-in ceremony ... it is Barack Obama's United States of America, and it is from there that a new chapter in the life of our country begins."
