Heli-History
It always sees to me that helicopters have changed very little in my lifetime. You still see the standard-issue Bell 206 Jetranger that would drop off misc bad guys in the A-Team, and the high-tech look of Blue Thunder or Airwolf is still pretty up to date.
C-Net has a photo gallery round-up of A Century Of Helicopters.
