Discourse and television texts
"Language as groups of statements comprised of rules and conventions that convey ways of thinking about the world. At any given moment there will be authoriative dominant discourses, which produce knowledge about the world and govern the way the world is talked about, when, where and by whom. At the same time, there are alternative or subordinate discourses that compete with these. Thus, in the Western world there is a particular dominant discourse about medicine, which governs the way illness and treatment are talked about, but there is also a subordinate discourse emanating in the field of homoeopathy which competes with this."
'Text' is the part of television we actually watch and consume. "The term 'text' is used in media studies to refer to the material that television produces, such as dramas, news, advertisements, documentaries and so on."
