An advertising network is like when you go to a birthday party and there are lots of different games and activities to do.
In the same way, an advertising network is a group of different websites and apps that companies can use to show their ads to people.
Think of these websites and apps like different rooms at the party. Each room has different games and activities, just like each website or app in the advertising network has its own unique audience and content.
Companies can pay the advertising network to show their ads on different websites and apps within the network, reaching more people than they could on their own.
Just like at the party, some rooms might be more popular than others. A company can choose which websites and apps they want their ads to appear on based on their target audience and popularity.
Overall, an advertising network is a group of different websites and apps that companies can use to show their ads to more people, like going to a party with lots of different rooms and games to play.
