There are many reasons people upload video content to YouTube, but increasingly one of them is the hope of making money through YouTube’s Partner Program. Creators can earn money through the adverts served alongside to their videos. The returns may be tiny, but as a channel gets more popular the revenue can steadily increase. However, YouTube is changing the eligibility rules today, and it makes monetization much more difficult. Until now, joining the Partner Program simply required a channel achieve 10, public views. From today, new channels will require 4, hours of watchtime within a month period and at least 1, subscribers.
