The theme is "Change You Can Believe In," and Colorado Gov. Bill Ritter has been announced as one of the night's speakers.

"We are very much looking forward to welcoming more than 75,000 of our closest friends to INVESCO Field at Mile High for this historic night," said Leah D. Daughtry, chief executive officer of the Democratic National Convention Committee. "Have no doubt -- every seat will be a great seat as we listen to Barack Obama communicate the urgency of the moment, highlight the challenges Americans are facing, and call on Americans to come together to change the course of our nation."
