PewDiePie -- who recently declared he will delete his YouTube channel once he reaches 50 million subscribers -- is the highest paid digital star of 2016.

The Swedish gamer -- whose real name is Felix Kjellberg -- made an estimated $15 million for the 12 months ending in June 2016, according to Forbes' recent ranking.

This is the second year the 26-year-old YouTuber has topped the list. His paycheck surged 20% from last year, when he made $12 million.

Kjellberg’s success is innately digital. He launched his channel by making “Let’s Play” videos, which showcase a gamer playing through a video game alongside footage of that player’s narration and reactions to the game.

His book This Book Loves You made the New York Times bestseller list and his YouTube Red series Scare PewDiePie was renewed for a second season. His second video game, PewDiePie’s Tuber Simulator, was downloaded more than 1 million times within 24 hours of its release.
