Have you ever noticed the little animation or picture that appears at the beginning of a movie or TV show? That's called a production logo. It's kind of like a company's signature or a way for them to show that they made the movie or show you're about to watch.
Just like when you write your name on a piece of paper, companies want to put their name on their movies and TV shows, too. And they want it to look cool and be memorable so that you will remember it and maybe want to watch more movies or shows made by that company in the future.
Different companies have different production logos. Some might have an animation of a cartoon character, while others might have a dramatic music score with the company's name appearing in a fancy font. The production logo usually only lasts a few seconds, but it's an important way for the company to show off its branding and get you excited to watch the movie or show.
