Have you ever listened to the radio? Well, now there is a special kind of radio called Internet radio. It is like normal radio but you listen to it on the internet.
When you listen to Internet radio, it can be hard to know how many people are listening at the same time because they are not all in the same place like in a normal radio station. So, people use something called audience measurement to keep track.
It is like counting how many people come to your birthday party. Companies use special tools to count how many people are listening to Internet radio at the same time. They can also find out what kind of music or stories people like to listen to the most.
This helps internet radio stations know what their listeners like and how popular they are. It also helps companies who want to advertise their products decide if they want to put their ads on that station or not.
So, to sum it up, audience measurement is a way to count and understand the people who listen to internet radio. Just like counting who comes to your birthday party, but bigger!
