Okay kiddo, so have you ever watched TV and noticed that some shows or channels have a special picture or symbol that appears on the screen? That picture is called a logo and it helps people know what they are watching or who it is coming from.
One of those logos belongs to a big TV network called CBS. Their logo is made up of a big blue eye that looks like it's watching you! This logo has been around since 1951, which is a really long time!
Now, some people might wonder why CBS picked an eye for their logo. Well, the idea behind it is that CBS wants to be like a watchful eye, always keeping an eye out for what's happening in the world and bringing it to you through their news programs and other TV shows.
So remember, when you see that big blue eye on your TV screen, that means you're watching something on CBS - a TV network that's been watching over you for over 70 years!
