The September 11 attacks of 2001, in addition to being a unique act of terrorism, constituted a media event on a scale not seen since the advent of civilian global satellite links. Instant worldwide reaction and debate were made possible by round-the-clock television news organizations and by the internet. As a result, most of the events were known by a large portion of the world's population as they occurred. The attacks themselves lasted less than two hours; the first hijacking commenced at approximately 8:14 am, and the final hijacked plane crashed at 10:03 am.
