So, you know how when you go to bed and dream things, you can see and hear all sorts of cool stuff in your head? Well, some people have a special job where they use their brains to make cool stuff happen on the internet!
That's the job of a Chief Digital Officer (CDO). They work for big companies and their job is to make sure that the company does really well on the internet.
They know a lot about technology, which is like the toys grown-ups use to make machines do stuff. They use their knowledge of technology to figure out new ways for the company to be more popular on the internet.
For example, let's say there's a company that sells toys. The CDO might make new web pages and fun videos and games for kids to play. Then more people will visit the company's website and maybe buy more toys!
The CDO's job is really important because a lot of people use the internet to buy things and find out about things. So, they make sure companies use the internet in the best way possible. That's why we need people like CDOs!
