    10. 10. communication from an ecological point of view The system reaches an equilibrium! <ul><li>The diffusion of communication technologies in a social community can be explained through the comparison with an ecological system </li></ul>
    11. 11. communication from an ecological point of view <ul><li>“ High interdependence ” and “ non-reversibility ” are important features of communication systems as well. </li></ul>Organization E-Mail Traditional mail Phone Fax E-mail Phone Mail Fax <ul><li>“ Old” communication technologies will have to re-negotiate their field of action with e-mail. </li></ul>
    12. 12. diffusion of innovation theories <ul><li>In a given social context, an innovation can be: </li></ul><ul><ul><li>Adopted -> “Winner” innovations </li></ul></ul><ul><ul><li>Not adopted -> “Loser” innovations </li></ul></ul><ul><li>Having a better technology is not enough for obtaining social acceptance. </li></ul><ul><li>How and why do people adopt or reject an innovation? </li></ul><ul><li>According to diffusion theories an innovation can be adopted if: </li></ul><ul><li>it has a better technology ; </li></ul><ul><li>it is supported by a well defined business model ; </li></ul><ul><li>it is compatible with the legal framework ; </li></ul><ul><li>it has social acceptance . </li></ul><ul><li>Let’s make some example… </li></ul>
    13. 13. diffusion of innovation theories <ul><li>Radio AM / FM </li></ul><ul><li>Radio FM was invented in 30’s. It has a better technology than AM radio, nonetheless it had almost no diffusion for three decades. </li></ul><ul><li>At the beginning of the 60’s it had a great diffusion and it dethroned AM radio in less than 10 years. Why? </li></ul><ul><ul><li>FM frequencies was regulated in 1967 by reserving space on the FM dial for new public radio station -> LEGAL FRAMEWORK ; </li></ul></ul><ul><ul><li>FM public radio station transmitted Rock’n’roll music -> SOCIAL ACCEPTANCE ; </li></ul></ul><ul><ul><li>The demand for FM technology increased by young people attracting a lot of investors for this technology -> BUSINESS MODEL . </li></ul></ul>
    14. 14. diffusion of innovation theories <ul><li>I-Pod </li></ul><ul><li>Example of a successful communication technology </li></ul><ul><li>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 </li></ul><ul><li>Very easy to use, it is considered a “must have” gadget by the social community -> SOCIAL ACCEPTANCE </li></ul><ul><li>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 </li></ul>
    15. 15. bibliography <ul><li>Materials published on: </li></ul><ul><li>Articles from prof. Cantoni's blog: </li></ul><ul><li>Reference book: Lorenzo Cantoni, Stefano Tardini, “Internet” , 2006, published by Routledge </li></ul>
