Usage: Do not use "broadcast" as an adverb to mean widely or abroad in modern English; instead, place the word "widely" after the verb (e.g., "The news was broadcast widely"). Reserve "broadcast" strictly for its verb form meaning to transmit signals or nouns referring to the content itself.
The word broadcast comes from combining broad and cast, first appearing in the mid-18th century to describe the agricultural practice of scattering seeds widely over a field. Its meaning later expanded to include sending radio or television signals out to a wide audience.
