A bumper in broadcasting is like a special message that helps you understand what you are about to see or hear. It is like a little preview or introduction that tells you what to expect.
Imagine you are at a friend's house and they want to show you a new toy. Before they show it to you, they might say something like, "Hey, check out this really cool toy! It has lots of buttons and it can light up!" This is like a bumper because it gives you an idea of what you are about to see.
In the same way, when you are watching TV or listening to the radio, a bumper can tell you what program or show is about to start. For example, if you are watching a cartoon and it is about to end, a bumper might come on and say, "Coming up next, a new episode of Adventure Time!" This tells you that Adventure Time is the next show that will be on.
Bumpers can also be used to remind you of important information, like a radio station's call letters or a TV network's logo. This is like when your mom puts a sticky note on your lunchbox so you remember to eat your fruit or drink your milk.
Overall, bumpers in broadcasting help you understand what you are about to see or hear, and remind you of important information. They are like little previews or reminders that make watching TV and listening to the radio a little bit easier to understand.
