Although there is considerable work in this area a formal theoretical model for any or all of the media is not available, particularly with reference to the notion of visual ethics.
Any formal theory of media ethics would be quantitative. To develop such a system, you would need to somehow measure the result of statements made (and their intonation) by the media and determine if there exists, and to what degree, an impact on policies or group action that directly affect a population or person for good or bad.
Well, I would believe in addition to this quantitative analysis - some interviews with some of the RETIRED politicians who will advise of their PLEASANT time with the harassing media!
Thankyou Mr. Inman and Ms Issa for your valuable contribution. I want to know if somebody else has worked on it, because by itself it looks like a humongous task
Not ethics, but quantitative media analysis, which can then be applied to ethics and media impact is done by a former employer of my media company, Media Tenor AG. They are based in Zurich, but have researchers around the world and in many languages.
If you do decide to order their materials, I may be of assistance to you in your research, as I am trained to analyze their internal system. Feel free to contact me if you have such an interest and I can put you in contact with the right people over there.
Most media analysis is non-formal and not quantitative, and doing qualitative, informal media analysis by interview as described by Theodora can be quite beneficial to analyzing media ethics as well. If you are purely interested in formal and quantitative media analysis, Media Tenor is the best place to start. There are some other companies who use computer analysis to determine media sentiment, but we are perhaps another 3-5 years before those programs will catch up to human accuracy in understanding media sentiment.
