Okay kiddo, so you know how sometimes you watch TV and the picture looks kinda fuzzy? Well, that's because the signal that brings the picture and sound to your TV is made up of tiny waves that travel through the air. And sometimes those waves can get messed up or lost on the way to your TV.
But a long time ago, people figured out a way to make the waves stronger and more clear, so the picture would look better. They did this by using something called an "analog" signal. That's just a fancy word for a type of wave that's been around for a long time.
But now we have something even better! It's called "digital" TV. Digital TV uses a different kind of signal that's made up of numbers, like your mommy's phone number. These numbers are really good at traveling long distances without getting lost or messed up. So when you watch digital TV, the picture and sound are much clearer and smoother than before.
But to make digital TV work, we had to change some things. We had to build new things called "digital antennas" that pick up the new kind of waves. And we had to make sure all the TVs and other devices in people's homes could handle the digital signal.
So a long time ago, the government said that everyone had to switch over to digital TV, because it was better and more reliable. They gave people a lot of time to get ready, and they even helped pay for some of the new antennas and equipment. And eventually, almost everyone made the switch to digital TV!
Now, when you watch your favorite shows or movies, you can see and hear everything much better than before. And that's all thanks to digital TV!
