The YouTube Stars Your Kids Love Decoded

This 7-year-old has been creating toy-demonstration videos (with the help of his mom, who directs and works the camera) since age 4. Now, with more than six million subscribers, the videos of Ryan playing with cars, trucks, superheroes, surprise eggs, and Play-Doh are some of the most viewed on the entire internet.
Quick take: Ryan ToysReview features tons of products, including expensive ones like kiddie cars. The family donates a lot of the toys to charity, but the "reviews" give the companies lots of publicity.
Best for: Preschoolers and little kids
