communication technology
Basic form of human communication is oral communication.
In centuries new ways of communication have been developed to facilitate and to enhance communication among humans.
Communication technology called-> “technology of the word”

communication technology Fax –Since 20th century
Like as mail but the legal view point for the authorization No need to use computer
Telegram –The first commercially telegraph cable was successfully completed on 25 August 1858.
Fax took some part of telegraph. Phone
Handles two types of information: signals and voice .

The system reaches an equilibrium!
The diffusion of communication technologies in a social community can be explained through the comparison with an ecological system
Computer mediated communication 11
communication from an ecological point of view “High interdependence” and “non-reversibility” are
important features of communication systems as well.
Organization
E-MailTraditional mail
Phone Fax E-mailPhoneMail
Fax
“Old” communication technologies will have to re-negotiate their field of action with e-mail.

diffusion of innovation theories In a given social context, an innovation can be:
Adopted -> “Winner” innovations Not adopted -> “Loser” innovations
Having a better technology is not enough for obtaining social acceptance.
How and why do people adopt or reject an innovation?
According to diffusion theories an innovation can be adopted if: it has a better technology; it is supported by a well defined business model; it is compatible with the legal framework; it has social acceptance.
Let’s make some example…
Computer mediated communication 13
diffusion of innovation theoriesRadio AM / FM Radio FM was invented in 30’s. It has a better technology than AM
radio, nonetheless it had almost no diffusion for three decades. At the beginning of the 60’s it had a great diffusion and it dethroned
AM radio in less than 10 years. Why? FM frequencies was regulated in 1967 by reserving space on the FM
dial for new public radio station -> LEGAL FRAMEWORK; FM public radio station transmitted Rock’n’roll music -> SOCIAL
ACCEPTANCE; The demand for FM technology increased by young people attracting a
lot of investors for this technology -> BUSINESS MODEL.
Computer mediated communication 14
diffusion of innovation theoriesI-Pod Example of a successful communication technology It has no battery to change. You can recharge it simply by connecting it to
the PC while downloading music on it -> BETTER TECHNOLOGY THAN OTHER MP3 PLAYERS
Very easy to use, it is considered a “must have” gadget by the social community -> SOCIAL ACCEPTANCE
It is supported by a platform (I-Tunes) in which you can legally buy music and services for your I-Pod from Internet -> BUSINESS MODEL AND LEGAL FRAMEWORK
