Innovation Decision Model
1) Knowledge – person becomes aware of an innovation and has some idea of how it functions,
2) Persuasion – person forms a favorable or unfavorable attitude toward the innovation,
3) Decision – person engages in activities that lead to a choice to adopt or reject the innovation,
4) Implementation – person puts an innovation into use,
5) Confirmation – person evaluates the results of an innovation- decision already made.

Market and Infrastructure Model
Lawrence Brown, Innovation Diffusion: A New Perspective
Adoption is limited by marketing and available infrastructure
Economic History Perspective
Lawrence Brown, Innovation Diffusion: A New Perspective
Consumers are rationale and wait to adopt when they can afford the innovation and when the innovation has dropped in price and is perfected

Media Replacement
Wilbur Schramm Functional Similarity – new media replace
in terms of time spent in use media that fulfill the same function
Proximal Similarity - new media replace in terms of time spent in use media that are consumed in the same space

Information Age
The Information Age, also commonly known as the Computer Age or Digital Age, is an idea that the current age is defined by the ability of individuals to transfer information freely, and to have instant access to information that would have been difficult or impossible to find previously. This idea develops from the concept of a digital age or digital revolution, and carries the ramifications of a shift from traditional industry that the industrial industrial revolution brought through industrialization, to an economy based on the manipulation of information, i.e., an information society.
Information Society
Daniel Bell – The Coming of Post-Industrial Society (1973)
By an information society, Bell that we have changed from a producer of goods (manufacturing) to a service economy and that theoretical knowledge, technology, and information become the major mode of commodity. More valued than physical laborers are information, and those who know how to create, assemble, and disperse. Information is normally costly to produce, but cheap to reproduce. Thus, the cost of producing the first copy of an information good (such as writing a book or recording a CD) is normally quite costly, but reproducing these items is often negligible.
