I haven’t seen this linked, but it’s a browsable archive of the week of TV on and after the 9/11 attacks: http://www.archive.org/details/911/day/20010911
That’s pretty incredible. Just looking at the time lines it’s very interesting which channels start covering it and when.
I’m also really interested at just how bad the reporting is given the number of stations who fumble around speculating on what caused the second explosion while their footage clearly shows the plane hitting the tower.
