The word 广播 (guǎngbō), meaning "broadcast", is formed by combining two meaningful characters into a new conceptual whole. The first character, 广 (guǎng), carries the core idea of "wide", "broad", or "expansive". The second character, 播 (bō), means "to sow", "to scatter", or "to spread". Thus, the term is constructed through a vivid metaphorical image: the act of widely scattering information or signals, much like a farmer sows seeds across a field, creating a perfect pictographic concept for the widespread dissemination of sound or programming.
