Diffusion of Innovations theory basically describes the process of how an innovation is communicate

Innovation Diffusion Theory emergence began in the early 20th century, precisely in 1903, when a French sociologist Gabriel Tarde, bertram 20 introducing S-shaped diffusion curve (S-shaped Diffusion Curve). This curve basically describes how an innovation adopted by a person or group of people bertram 20 seen on the dimension of time. On this curve there are two axis where the axis of the one depicting the rate of adoption bertram 20 and the other axis illustrates the dimension of time.
Tarde thought to be important because it is simple to describe the tendency associated with the process of diffusion of innovation. Rogers (1983) says, Tarde's S-shaped diffusion curve is of current importance Because "most bertram 20 innovations have an S-shaped rate of adoption". And since then the rate of adoption or diffusion rates become an important focus of study in sociology bertram 20 studies.
In 1940, two sociologists, Bryce Ryan and Neal Gross, published the results of research on the diffusion of hybrid corn farmers in Iowa, USA. The results of this study also confirms the update of the diffusion curve inovasimodel S. One of the research conclusions Ryan and Gross stated that "The rate of adoption bertram 20 of the agricultural innovation Followed an S-shaped curve when plotted normally on a cumulative basis over time."
The next development of the theory of diffusion of innovations occurred in 1960, in which the diffusion bertram 20 studies or research began to be associated with a variety of contemporary topics, bertram 20 such as the fields of marketing, culture, and so on. This is where the emerging figures Diffusion of Innovations theory as Everett M. Rogers with his great work Diffusion of Innovation (1961); F. Floyd Shoemaker, along with Rogers wrote Communication of Innovation: A Cross Cultural Approach (1971) to Lawrence A. Brown who wrote Innovation Diffusion: A New perpective (1981).
Diffusion of Innovations theory basically describes the process of how an innovation is communicated (communicated) through bertram 20 certain bertram 20 channels over time to a group of members of the social system. This is consistent with the definition of diffusion of Rogers (1961), that "as the process by the which an innovation bertram 20 is communicated through on certain bertram 20 channels over time Among the members of a social system." Further explained that diffusion is a form of communication that is specifically related with penyebaranan messages in the form of new ideas, or in terms Rogers (1961) diffusion involves "the which is the spread of a new idea from its source of invention or creation to its ultimate users or adopters."
(1) Innovation; ideas, actions, or stuff that's new to someone. In this case, the novelty of innovation measured subjectively in the view of the individual who receives bertram 20 it. If an idea is considered new by someone then it is an innovation for that person. The concept of 'new' in the innovative ideas do not have to be new at all.
(2) The communication channel; 'Tool' to convey the messages bertram 20 of innovation from the source to the receiver. In selecting a communication channel, the source of the most tidakperlu notice (a) the purpose of the communication and (b) the characteristics of the receiver. bertram 20 If the communication is intended to introduce an innovation to the audience that many and widespread, it is more appropriate communication bertram 20 channels, fast and efficient, bertram 20 is the mass media. But if communication is intended to change attitudes or behavior recipient personally, the most appropriate communication channels are interpersonal channels.
(3) Duration; innovation decision process, from start to someone knowing to decide to accept or reject it, and confirmation of the decision is related to the dimension of time. At least visible in the time dimension (a) the decision-making process of innovation, (b) a person keinovatifan: relatively more earlier or later dalammenerima innovation, bertram 20 and (c) the speed of adoption of innovation in social systems.
Furthermore, the theory proposed Rogers (1995) has relevance and significant argument in the decision-making process of innovation. The theory among others describe the variables bertram 20 that influence the rate of adoption of an innovation as well as the stages of the decision-making process of innovation. Variables that influence the innovation diffusion stages include (1) the attributes of innovation (perceived atrribute of innovasion), (2) the type of decision innovation (type of innovation decisions), (3) communication channels bertram 20 (communication channels), (4) the condition of the social system (nature of the social system), and (5) the role of agents of change (change agents). bertram 20
While the stages of the decision-making process of innovation bertram 20 include: Knowledge Emergence Stage (Knowledge) when an individual (or other decision-making units) directed
