MUMBAI: National Geographic Channel (NGC) in the US has announced that its special Inside 9/11 managed to do well on the ratings front.

The broadcaster states that the mini-series that looked at the events that took place four years ago was viewed by almost 18 million people over two nights.

NGC US claims to reach 55 million homes. 24 per cent of its audience tuned in to Inside 9/11 over the two nights on 21 and 22 August 2005. Inside 9/11 led to two consecutive record prime ratings for the network -- both in households and demos, landing NGC among the top three cable networks in prime for the first time on Sunday night. The special also led the network to its highest rated day average, highest rated week, and set the stage for the quarter to set a new record.

NGC broke a 2.0 rating for the first time with Part One: War on America which earned a 2.5 HH/2.0 P25-54 rating and then achieved an impressive 3.6 HH rating with Part Two: Zero Hour which earned a 2.9 P25-54 rating. More than 6 million persons 2+ tuned in to the first part. NGC will again air the four hour special on 8 September and on 11 September.

Inside 9/11 presented a perspective on that day that aimed to go beyond what's been widely reported to reveal a clearer picture of events. Inside 9/11 traces the timeline that led up to the deadly attacks, spanning decades and circling the globe to lay bare the roots of Al Qaeda and the transformation of Osama bin Laden from fund-raiser to terrorist mastermind. The mini-series also deconstructs the fateful day, tracking the movements of all four terrorist teams and patching together the ad hoc response of the US government.
