The term "rbtv" functions grammatically as a proper noun. As an initialism, acronym, or specific brand identifier, it names a unique and specific entity, organization, concept, or product. Its primary role in a sentence is to serve as a subject, object, or complement, just as any other noun would.
While it may occasionally be used as a noun adjunct, where it modifies another noun (e.g., "the rbtv framework" or "rbtv content"), its core part of speech remains a noun. In such constructions, it acts in an adjectival capacity but is not itself an adjective. This is a common linguistic pattern where one noun is used to qualify another, similar to phrases like "business school" or "computer science," where "business" and "computer" are fundamentally nouns.
Therefore, for the purpose of constructing grammatically correct and clear sentences within the article, the term should be consistently treated as a proper noun. This classification dictates its syntactic behavior, such as its ability to be preceded by articles in specific contexts (e.g., "the RBTV of the 1990s") and its function as the central component of a noun phrase.
