2. Large Scale
2.1. Tains
2.1.1. Trains are very popular modes of transport and currently don't have ads on them, this would mean a very low price for the ads and would be viewed by thousands of people, the only problem being there would not be an effective way of targeting specific groups, so it would not be the most effective way.
2.2. Areoplanes
2.2.1. Adding an advert on the outside of a plane would be very easy and noticeable. However it would only be visible to a few passengers. However I think advertising in airports and areoplane magazines could be a very cost effective and efficient method of advertising.
