Final answer:
A blockbuster film is considered high definition or 'hot media' in McLuhan's terms, due to its high level of detail and low audience participation, making the statement True when corrected for terminology.
Step-by-step explanation:
The statement that McLuhan said content was high and low definition is not entirely accurate in the context of his work. Marshall McLuhan, in his book Understanding Media: The Extensions of Man, discussed media in terms of hot and cold media, not high and low definition. Hot media are those that are high in definition, demanding little involvement from the audience because they provide a wealth of data. Examples are films and photographs, which provide detailed visual information. Cold media, on the other hand, are low in definition and require high audience participation to fill in the gaps, such as comics or telephone conversations. Therefore, a blockbuster film, with its detailed visual and auditory information, would indeed be an example of high definition or 'hot media' in McLuhan's terms. The question is based on a misinterpretation of McLuhan's concepts; however, if we correct the terminology to align with McLuhan's original meaning, the statement about a blockbuster film being an example of high definition is True.
