Okay kiddo, so you know how sometimes you see airplanes flying in the sky with big banners attached to them? That's called aerial advertising! It's a way for companies to get their message out to lots of people all at once.
Basically, the company pays to have their message put on a big banner or sign, and then that banner gets attached to an airplane or helicopter. The pilot flies around in the sky, and everyone below can see the message on the banner.
Aerial advertising can be really effective because it's hard to ignore. When you see a big banner flying in the sky, you usually can't help but look up and see what it says.
Of course, it's not just any message that can go on the banner. Aerial advertising is regulated by the government to make sure that the messages are appropriate and not offensive. So if you see a banner flying in the sky, you can trust that someone has approved the message!
Overall, aerial advertising is a pretty cool way for companies to get their message out to lots of people. And for those of us on the ground, it can be a fun and interesting thing to see in the sky!
