More than 84,000 people jammed into Invesco Field at Mile High stadium to hear Barack Obama's historic acceptance speech, city officials say.

Nancy Kuhn of Denver's public works department says the figure is based on the number of credentials that were scanned as delegates, individuals and news media entered the football stadium where Obama was accepting the Democratic presidential nomination Thursday night.

The stadium normally holds 76,125 people, but additional seats were placed on the football field where the Denver Broncos play.
