" The actual implementation of the controller object can vary quite a bit, but the idea of an object to 'transform' events to changes in data and execution of methods is the essence of this pattern. What does "event driven" mean? Was there ever an application which did not respond to user events . . ? Just because an application responds to events does not mean it is "event driven". Event driven means it spends much of its time waiting for an event and then takes action if and when an event occurs. Contrast this with some programs that do not respond to events at all, but simply do their job and terminate. For example, an operating system command to display the current time. Chinese Female Model It displays the time and is done; it does not wait for events.

" MVC is Move Character in the IBM System/360 instruction set The propaganda model is a theory of political economy advanced by Edward S. Herman and Noam Chomsky that seeks to explain the supposed systemic political biases of the mass media in terms of structural economic causes. Overview First presented in their 1988 book Manufacturing Consent: the Political Economy of the Mass Media, the propaganda model views the private media as businesses selling a product — readers and audiences (rather than news) — to other businesses (advertisers). The theory postulates five general classes of "filters" that determine the type of news that finally gets published in news media. These five are: Ownership of the medium Medium's funding sources Sourcing Flak Anti-communist ideology The first three (ownership, funding, and sourcing) are generally regarded as being the most important. Although the model was based mainly on the characterization of United States media, Chomsky and Herman believe the theory is equally applicable to any country that shares the basic economic structure and organizing principles which the model postulates as the cause of media biases. The filters Ownership Herman and Chomsky argue that since all mainstream media outlets are embodied in large corporations, which are themselves often part of much larger conglomerates (e.
