Explanation:
In markets where competition is very intense, companies are not able to keep on competing in prices forever, as at some point their cost structures prevents sucessive price lowerings. Therefore, companies are forced to use alternative strategies to defeat their competitors and to attract larger shares of consumers to demand their products.

This new feature has been achieved through the implementation of a new tecnique in the production process (ex: new materials for the packaging) together with an innovative and sucessful marketing campaign.
