>It is fueled by the advertising race (companies bidding against each other to complete for consumer's attention) Exactly but I would like to add that the companies which are in the advertising race are most likely monopolistic competitors[0] or in another words, they have very similar products and the only way to reach customers and to build brand is to invest heavily in the advertising. That's why advertising will stay strong and viable as a business model for very long time. >In other words, we injected money into that sector, so we saw it growing. But if the money is not used efficiently and if no innovations come about then no matter how much you invest, you won't see a sector growing.
