YouTube rolls out Hype, which lets users boost creators with under 500K subscribers via a hype button that gives videos points, in the US and 38 other countries

A quick recap of how it works: Viewers have the opportunity to hype up to three videos per week for a creator with under 500,000 subscribers. When a video is hyped, it receives points, giving it a chance to end up on a new ranked leaderboard that you can find in the Explore menu. To level the playing field, hype gives smaller creators a bigger boost. The fewer the subscribers, the bigger the bonus, giving the most authentic emerging creators a better opportunity to get noticed.
