means A person or company that sends radio or television programs out to a wide audience.

from Built from 'broadcast,' which originally meant scattering seed widely by hand across a field — a farming term from the 1700s. In the early 1900s, radio engineers borrowed the image: instead of sowing seed, they were sowing signals, flinging sound indiscriminately into the air for anyone within range to catch. 'Broadcaster' followed naturally, turning sowers of wheat into sowers of words.
