A few months ago, a Mumbai-based 13-year-old boy was in the news when his courier-based food delivery app became very famous in no time. By 2020, this boy could earn one billion rupees per annum!

There is someone younger who is in the news for an even more surprising reason. The boy is all of seven years old. He is Ryan, a YouTube star from the US. The boy is known for reviewing the latest toys in the market. His YouTube channel has 17.3 million subscribers.

Ryan's toy reviews are taken seriously by many parents across the world. And guess how much he has earned on his YT channel? 22 million dollars. Forbes has said that his is the highest grossing YT channel of the year. It has garnered 26 billion views so far.

Retail giants like Walmart have seen sales of toys jumping when Ryan reviews them. Walmart has even launched an exclusive line of toys named after the boy!
