LOS ANGELES — It’s been quite a year for Noen Eubanks.

Last September, he was a high school senior living in the suburbs of Atlanta, acting in high school plays and planning to study video game design one day. Like so many before him, he was also just trying to get through adolescence without being teased.

Then, he started a TikTok account, posted a short video of a joke he wanted to show his older brother, and forgot about it. He came back later to find about 100 views — a lot, he thought at the time. So he kept at it. “I lost my mind,” he said.

Today, he’s got over 5 million subscribers and is living in Hollywood Hills, having been hired as the new face of Kyra TV, a Youtube media company with a Gen Z fan base, earlier this summer. He has a producer, who develops content and brand partnerships for him, a clothing line in the works (it will debut with a sweatshirt) and a salary.

Next, Mr. Eubanks, 18, joked , he might “buy a country.”

“I just kind of went with it,” he said. “Sometimes you just have to let go, because if you hold on to things you’re basically fighting yourself.”
