ELI5: Explain Like I'm 5

HD DVD

Okay kiddo, have you ever seen a DVD? It’s a little shiny disk that you put into a machine called a DVD player, and it plays movies or TV shows on your TV.

Well, HD DVD is kind of like that, but it’s a special type of DVD that can hold even more information and has better quality. “HD” stands for “high definition,” which means that the movies and shows look even better than on a regular DVD.

HD DVDs were created to try and replace regular DVDs, but they never really caught on. One reason was because there was a competing format called Blu-ray, which was backed by big companies like Sony and had more support.

So even though HD DVDs were cool and had good quality, they didn’t become as popular as regular DVDs or Blu-rays. But some people still use them and enjoy watching their movies and shows in high definition!
