Very, very few YouTube video creators make any real money off of those pre-roll ads, but that might soon change. Google has launched Fan Funding, a new way to tip your favorite YouTube stars directly from the video. Here’s how it works: when you play a video from a channel that accepts donations, you’ll see a little icon in the top left corner of the video. Hovering over it will reveal a banner, in some cases. Or you might see a pop-up directly on top of the video where you will be asked how much money you wish to donate.
