A Commonwealth Broadcasting Association (CBA) is an organization for countries that used to be part of the British Empire. These countries share similar values and cultures, and the CBA helps promote communication and cooperation among their broadcasters.
Imagine you're playing with your friends and you want to talk to someone who is far away. You might use a telephone or walkie-talkie to communicate. Similarly, broadcast organizations in different countries use different ways to communicate with each other, like TV, radio, and internet.
Now picture the CBA as a group of grown-ups who help people who run TV and radio stations in different countries talk to each other. They teach people in different countries how to create good programs, how to use technology, and how to talk to people from other cultures.
The group also shares news and information, so you can learn about what is happening in different parts of the world. They want to help people understand each other better and make friends across borders.
In summary, the Commonwealth Broadcasting Association is like a big group of friends from countries that used to belong to the same empire. They help each other talk and share information, so everyone can learn and have fun together!
