ELI5: Explain Like I'm 5

Format wars

Okay kiddo, so you know how sometimes there are different types of toys or games that do the same thing but look or work differently? Well, that happens with technology too!

When people make things like DVDs or video games, they need a way to store all the information on them. The way they do that is by creating a format, which is like a special recipe for how to organize all the information.

Sometimes, different companies or groups come up with different formats for the same kind of thing, like Blu-ray or HD DVD for movies. And that's where the format wars begin!

People who like one format might think it's better than the other, and they'll argue about it a lot. And sometimes, stores or companies will decide to only sell one format instead of both, so that makes people even more upset.

But eventually, one format usually becomes more popular and the other one kind of fades away. And then people can stop arguing about it and just enjoy their movies or games. Does that make sense, kiddo?
