On April 6, 2017, YouTube announced that in order to "ensure revenue only flows to creators who are playing by the rules", it would change its practices to require that a channel undergo a policy compliance review, and have at least 10,000 lifetime views, before they may join the Partner Program. On January 16, 2018, YouTube announced tighter thresholds where creators must have at least 4,000 hours of watch time within the past 12 months and at least 1,000 subscribers.
In December 2012, two billion views were removed from the view counts of Universal and Sony music videos on YouTube, prompting a claim by The Daily Dot that the views had been deleted due to a violation of the site's terms of service, which ban the use of automated processes to inflate view counts. This was disputed by Billboard, which said that the two billion views had been moved to Vevo, since the videos were no longer active on YouTube. On August 5, 2015, YouTube removed the feature which caused a video's view count to freeze at "301" (later "301+") until the actual count was verified to prevent view count fraud. YouTube view counts once again updated in real time.
YouTube earns advertising revenue from Google AdSense, a program which targets ads according to site content and audience. The vast majority of its videos are free to view, but there are exceptions, including subscription-based premium channels, film rentals, as well as YouTube Premium, a subscription service offering ad-free access to the website and access to exclusive content made in partnership with existing users.
