" There are twelve different types, or "flavours", of fermions in the Standard Model. Amongst the proton, neutron, and electron, those fermions which constitute the vast majority of matter, the Standard Model considers only the electron a fundamental particle . The proton and neutron are aggregates of smaller particles known as quarks, which are held together by the strong interaction. The fundamental fermions in the Standard Model are given in the table.

" 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. g. Westinghouse or General Electric). Such conglomerates frequently extend beyond traditional media fields, and thus have extensive financial interests that may be endangered when certain information is widely publicized. Star War Model Ship Thus, according to this reasoning, news items that most endanger the corporate financial interests that own the media will face the most bias and censorship. The authors claim that the importance of ownership filter is the fact that corporations are subject to shareholder control in the context of a profit-oriented market economy. "
