The price charged for products and services is set artificially low in order to gain market share. Once this is achieved, the price is increased.
example: This approach was used by France Telecom and Sky TV. These companies need to land grab large numbers of consumers to make it worth their while, so they offer free telephones or satellite dishes at discounted rates in order to get people to sign up for their services. Once there is a large number of subscribers prices gradually creep up. Taking Sky TV for example, or any cable or satellite company, when there is a premium movie or sporting event prices are at their highest – so they move from a penetration approach to more of a skimming/premium pricing approach.
