The International Council for Press and Broadcasting is like a group of grown-up friends who work together to make sure that the news and television shows you watch are fair and truthful. They help make sure that the people who report the news and make TV shows follow some important rules, like telling the truth and being fair to everyone they talk about.
Just like how your parents might make rules for you to follow, the International Council for Press and Broadcasting makes rules for people who work in the news and television industry. They also help solve problems if some rules aren't being followed, just like how your teacher might help solve problems if someone in your class isn't following the rules.
So basically, the International Council for Press and Broadcasting is like a big group of grown-ups who help make sure that everything you watch on TV is fair and truthful, and that people who work in the news and television industry follow some important rules.
