I love watching videos of bloggers on YouTube, and there are quite a few fafavorites among them. For example, the blogger PewDiePie, I think many people know him as a blogger with 90 million viewers. He rose to fame with his yearsplays - videos in which he played games and commented on them. Now he makes shows. His channel has been the most popular for years, and how, I wonder, did he achieve that popularity?
