We might ask whether the cost of advertising is paid for by the manufacturer or by the consumer.Since advertising forms part of the cost of production, which has to be covered by the selling price, it is clear that it is the customer who pays for advertising.However, if large scale advertising leads to increased demand, production costs are reduced, and the customer pays less. It is difficult to measure exactly the influence of advertising on sales.When the market is growing, advertising helps to increase demand.When the market is shrinking, advertising may prevent a bigger fall in scales than would occur without its support.What is clear is that businesses would not pay large sums for advertising if they were not convinced of its value to them.
