Cronkite School's Steve Doig on inaugural crowd numbers

Journalism professor Steve Doig says that estimating the size of crowds at mass public events is more about public relations than a true estimation.

"Whether the crowd is gathering for an anti-war protest, a sports team's victory parade, a golf tournament, a pope's outdoor Mass or the swearing-in of the most powerful man on Earth, organizational reputations and personal egos are ballooned or deflated by public perceptions of whether the crowd is surprisingly large or disappointingly small," Doig says.
