Matt Wardman reminded me that not all virals rely on the web.
This one from some BBC/MSM petrolhead program relied on 'old media':
2m + views. All from old media promo.
The 'response' videos' (there are 20) sent me into a haze. But it's a 'demographic'.
I clicked around a wee bit and this vid on Hammond's subject is the real deal, far more interesting than their efforts. Didn't go viral, though.
Neither did this.
