Consider two cigarette companies, PM Inc. and Brown Inc. If neither company advertises, the two companies split the market. If they both advertise, they again split the market, but profits are lower, since each company must bear the cost of advertising. Yet, if one company advertises while the other does not, the one that advertises attracts customers from the other.
