"Activated content" refers to something that happens when you interact with certain things online, like a website or a video. You know how sometimes you might click on a button or type something into a box and then something else happens? That's activating content!
It's like when you open a present - you have to do something to see what's inside. When you click on a video or share a post on social media, that content becomes "activated" because it starts to do something new. This could mean showing you more information or playing a video, among other things.
Think of activated content like a secret code that unlocks something special. The more you interact with different things online, the more content you will activate and discover!
