They share everything from video game streams to daily vlogs, turning their hobbies into potential careers before they even finish high school. This digital stage offers incredible opportunities for creativity and entrepreneurship.

In Vietnam, this trend is clearly visible with creators like Jenny Huynh. At a young age, she captured the attention of millions of Vietnamese teenagers by sharing content about her life in America. Her videos, which are often simple and relatable, resonate deeply with her peers. Fans feel a personal connection to her, and their support has helped her become one of the most well-known young creators in the country, proving that you don't need a TV show to be a star.
