YouTuber
The video sharing site YouTube relies on volunteers, known as YouTubers.
YouTube embeds advertisements in (most of) the videos it shares. Once a video has passed a thresh-hold of number of views YouTube pays contributors a modest share of the revenue it collects.
Surprisingly, some of the most prolific YouTubers have become wealthy. Most YouTubers who receive a share of YouTube's advertising revenue only collect hobby revenue.
Many YouTubers have voiced frustration with YouTube relying on opaque rules for calculating YouTube's share of revenue, and for them changing their charging algorithm.
Some YouTubers supplement the income sharing from YouTube by providing their viewers to directly support their efforts. Some YouTubers have enrolled with firms who enable their viewers to enter into a regular subscription, that pays them a predictable income. A firm called Patreon is the most prominent of these firms. Still more YouTubers supplement their income by including segments within their video encouraging their viewers to buy particular products and services.
