覚え方のコツ Memory Tip
broadcasting は broadcast「放送する」に -ing をそのまま付けた形で、ここでは活動・産業としての「放送」を表す名詞です。work in broadcasting、digital broadcasting、live broadcasting の組み合わせを覚え、個々の番組を指す broadcast と区別しましょう。
Start with broadcast, literally built from broad and cast: the image is of sending something out widely. Add -ing without changing the base spelling to form broadcasting. As a noun, it refers to the activity, technology, or industry rather than one individual program. Common combinations include work in broadcasting, digital broadcasting, public broadcasting, and live broadcasting. Picture a signal spreading from one station to many listeners or viewers; that wide distribution connects the original word parts with the modern media meaning.

broadcasting の語源・成り立ち Etymology
broad（広い、古英語brād）+ cast（投げる、古ノルド語kasta）で「広くまき散らす」が原義。元は農業で種を広くまく意味だったが、ラジオの登場で「電波を広く届ける＝放送」の意味になった。関連語：broadcast（動詞）、broadcaster。
Broadcasting is formed from broadcast plus -ing. Broadcast combines broad with cast and originally described scattering seed widely over a field rather than placing it in rows. In the early twentieth century, the word was adopted for radio signals sent widely to many receivers. Broadcasting then became the standard noun for this activity and later expanded to television and internet-based transmission.
