The mediator also comprises means (7) for processing response data referring to responses of the users to the attention area content, as well as means (8) for transmitting the processed response data and the distribution price to the suppliers. Finally, the mediator comprises means (9) for (periodically) receiving, from the suppliers, a price bid for the distribution of a new attention area content, replacing the attention area content supplied by the preferred supplier, as well as means (10) for mutually comparing each received price bid and the actual distribution price and for selecting as new preferred supplier, the supplier offering the best price.
