My Sales experience is limited. I guess it depends on the type of product. For anything complex, I would think that it must be face to face. And it should be a short pitch. I remember one sales company in particular, that used to send their salesmen from business to business in the US with a prepared pitch. Tough work. maybe the distribution of a video would be similar to email sales campaigns where a huge volume of potential customer is targeted and all it takes is a few to make money?
Anyway I can't see how removing the F2F personal aspect is a good thing.
