There are many channels through which a newspaper can be commercially distributed - most often they are sold through supermarkets and corner shops or distributed for free at train stations or from the street.
This newspaper will be distributed solely through the train station itself, but will also have the unique advantage of a continued distribution through the train system. As passengers take and then subsequently leave the newspaper on the train, it is transported further, with the potential to reach audiences across the city and further afield.
This is the simplest way to distribute across a wide area whilst investing the least amount of time and money. It would also allow for a randomised distribution method meaning a wider and more varied audience would be exposed to the publication every day.
The newspaper would be distributed freely at Concorde station so as to encourage a more disposable element and ensure a selection of copies are left on the metros for other commuters to find and read.
