Currently, technology is common to everybody. Every people know how to use a technology. Design of gadgets is increase in consumers tastes. Consumer tastes also increase in a multiplication and choice in media channels and content.

Technology providers need to know their needs, preferences, tastes and desires and how these will shape the future patterns of demand.

Types of  Technology
According to book of the appropriate technology: problems and promises edited by Nicolas Jequier, technology movement is not only to develop new technology, but also to build up an innovation system. This can be tackled from two complementary angles which is production and consumption. Production is represented by the inventors who develop a new technology, manufacture a new product or provide a new types of service. Consumption is represented by the people who will buying or using these new product or services. These two aspects are closely inter-linked and any attempt to build an effective innovation system must consider them simultaneously.
There are three types of technology. First is private technology, second is community technology and third is public technology. Private technology is which often takes the form of consumer goods and especially durable consumer goods (the tin roof, the radio, etc.) and whose introduction depends almost exclusively on the decision of the individual and his family. Community technology is which include not only basic infrastructures like water supplies, education, transport networks or drainage systems, but also most of the production technologies of the individual farmer. Infrastructures are by nature a community technology, but so are most of the production technologies since they touch upon the communities collective goods (land, water, economic relations, social structures, etc.). public economy represented by the large industrial firms which produce consumer goods and the national institutions which supply certain basic services.
