So, you know when you watch a TV show or movie or play a game and sometimes there's a little commercial in the middle? That's called an advertisement.
Well, sometimes companies want to make their advertisements really interesting and fun to watch, so they make them into something that feels more like a TV show or game or movie.
That's where advertainment comes in! It's a mix of advertising and entertainment.
Companies make their advertisements entertaining so that people will want to watch them and they'll remember the product or service being advertised. They might make a funny video or a cool game that people can play.
So, the next time you see an advertisement that's really fun to watch, remember that it's called advertainment!
