Hot Media
Hot media, Marshall McLuhan mentioned on his book understanding media, is a high-resolution, and low-involvement media, such as radio, film. It provides audiences sufficient and vivid information. However, audiences have been deprived of opportunities for participation, and their information allows to release through the rigorous editing. Thus, the audiences can only passively receive information.
McLuhan cited some examples of hot media: photographs are high-definition. People do not need to fill in some of the content; broadcasting is hot medium, because it clearly and profoundly provides a large number of high-resolution auditory information. Teacher lecture is hot medium. The entire teaching process is clear, full, unidirectional transfer, in order to making students understand the information, and students are lowly involved in the information distribution.
