Do you want a real ELI5 answer?
Everyone carries a phone with them all the time. That phone is always turned on and telling on you. It tells where you are, like if you are at school or at home.
Well, because everyone else has a phone too, the phones can tell who is in the same class because all those phones are together all day long.
So when one person in your class buys a Paw Patrol toy, or watches a lot of Paw Patrol on YouTube, their phone says “hey this kid really likes Paw Patrol, maybe their friends from school would too” and starts telling all the other phones about Paw Patrol.
Now, it probably looks crazy if you were just playing Paw Patrol at school and suddenly your phone is showing you Paw Patrol. How did it know?
Their phone told your phone. Computers are so fast at telling each other things that sometimes your phone will hear about it before you hear it from your friend. And sometimes your phone will show it to you at just the right time that it looks crazy, but it’s really not.
