This collection contains television news programs recorded live from around September 11, 2001 by the non-profit Television Archive to help patrons research this important part of United States history. These materials were available on the televisionarchive.org site from October 11, 2001 through 2003.

These are lower quality, streaming versions of the 9/11 Archive MPEG's that were discovered by user 'gangsta' on February 22nd. But they are all there, all television footage of September 11th, 12th and 13th from CNN, FOX, ABC, CBS, BBC and NBC is now available for online viewing.

This is a HUGE resource for 9/11 research!

Unfortunately the high quality MPEG's are no longer available for download but chances are that they are all in the public domain by now and will be spread as torrents.
