Another internet star has scored a book deal. PewDiePie, aka Felix Kjellberg, aka that guy who does those gaming videos on YouTube, has written a book. Kjellberg's magnum opus, titled This Book Loves You, is being published in October in the US, UK, Germany, France, Sweden, and Norway. It features 250 pages of "indispensable advice and inspirational quotes" including, according to its Amazon page, gems like "You can never fail if you never try" and "Don’t be yourself. Be a pizza. Everyone loves pizza."

Kjellberg isn't the first YouTuber to leverage his fame with a book deal (online stars such as Grace Helbig and Shane Dawson have already published best-sellers), but he is the biggest. With 37 million subscribers, the Kjellberg is by far the most popular person on the site, with over 9 billion views and counting across all his videos, and annual revenue of around $4 million, according to one report in 2014. Popularity like this is extremely bankable, as Kjellberg's publishing deal with the Penguin Randomhouse subsidiary Razorbill proves.
