Some 84,000 people packed Denver's Invesco Field at Mile High to see Barack Obama make history.
The Illinois senator has become the first African American to accept the presidential nomination of a major political party.
Local officials say the stadium held more than its normal capacity for Denver Bronco football games because many extra seats were placed on the field.
There were constant flashes throughout the stadium from those
trying to get a visual record of the event.
When Obama's speech concluded, pyrotechnics spewed from the rear
of the podium. Streamers dropped on Obama, his family and running
mate Joe Biden and his wife, who joined him in waving to the crowd.
Obama says the nation has had enough of "broken politics" and "the failed policies of George W. Bush."
Obama promised to cut taxes for nearly all working-class
families, end the war in Iraq and break America's dependence on
Mideast oil within a decade.
He also attempted to link his criticism of President Bush to
John McCain. He said McCain is worthy of respect for his service to
the nation, but that when it comes to the problems of working
people, McCain "just doesn't get it."
He said electing McCain would mean four more years of the last
eight and that he welcomes a debate on the issues.
