broadcast
Broadcast describes something sent out to many people through radio, television, or the internet.
Explanation at your level:
You use broadcast when you talk about TV or radio. For example, a broadcast show is a show you watch on your television. It means many people watch it at the same time.
When something is broadcast, it is sent to many people. You see broadcast news on your TV every day. It is a common word for media and technology.
The adjective broadcast relates to the transmission of programs. We often use it in phrases like broadcast media to describe television and radio stations. It means the information is distributed to a large audience.
Beyond media, broadcast can describe any information sent to a wide group. If a company sends a broadcast message, they are notifying everyone at once. It implies a one-to-many communication style.
In an advanced context, broadcast denotes the wide dissemination of data or signals. It is frequently used in technical environments, such as broadcast networks or broadcast packets in computing. It captures the nuance of simultaneous, non-targeted transmission.
Historically rooted in agriculture, broadcast now serves as a metaphor for the mass proliferation of information. It characterizes the shift from interpersonal communication to mass media, reflecting how modern societies consume information. Its usage in academic and technical discourse underscores the scale and reach of modern connectivity.

When we use broadcast as an adjective, we are usually talking about the world of media. Think of your favorite television show or a live radio update; these are broadcast programs. It implies that the content is being sent out from a central source to reach as many people as possible simultaneously.
Beyond media, you might hear it used in a more general sense. If you broadcast a message to a group of people, you are making sure everyone gets the same information at once. It’s all about reaching a wide audience without needing to speak to each person individually.
The word broadcast has a fascinating agricultural history. It comes from the combination of 'broad' (wide) and 'cast' (to throw). Originally, it was a farming term used to describe the method of sowing seeds by throwing them widely over a field by hand.
It wasn't until the early 20th century, with the invention of radio technology, that the word took on its modern meaning. Just as a farmer would scatter seeds across a field, radio towers began 'scattering' sound waves across the airwaves to reach listeners everywhere. It is a perfect example of how language evolves alongside technology!
You will most often hear this word in professional or technical contexts. Common collocations include broadcast media, broadcast journalist, or broadcast quality. These phrases help define the specific industry standards for audio and video transmission.
In casual conversation, you might hear someone say, 'It’s a broadcast email,' meaning the same message was sent to the entire company. While it is a standard English word, it leans slightly toward formal or professional registers because of its association with news and telecommunications.
While 'broadcast' itself isn't always the core of an idiom, it appears in phrases like 'broadcast to the world', which means to tell everyone a secret or news. Another is 'broadcast news', referring to the industry itself. You might also hear 'to broadcast one's intentions', which means to make your plans very obvious to others, often unintentionally. These expressions highlight how the word implies making something public rather than keeping it private.
The word broadcast is interesting because its past tense and past participle are also broadcast (though 'broadcasted' is sometimes heard in casual speech, it is often considered incorrect by purists). In British and American English, the pronunciation is similar: /ˈbrɔːdkɑːst/.
The stress is on the first syllable: BROAD-cast. It rhymes with words like 'forecast', 'podcast', and 'low-cast'. As an adjective, it is usually placed before a noun, such as 'a broadcast signal' or 'a broadcast tower'.

It was purely a farming term until the 1920s.
