The SEC late last year prodded the company to explain why it doesn’t share YouTube data, according to regulatory filings in February. Accounting rules require companies to disclose revenue for operating segments that account for 10% of a company’s total revenue, profit or combined assets. YouTube’s numbers are included in Alphabet’s advertising figure.

Some YouTube videos have themselves had a direct effect on world events, such as Innocence of Muslims (2012) which spurred protests and related anti-American violence internationally.[269] TED curator Chris Anderson described a phenomenon by which geographically distributed individuals in a certain field share their independently developed skills in YouTube videos, thus challenging others to improve their own skills, and spurring invention and evolution in that field.[254] Journalist Virginia Heffernan stated in The New York Times that such videos have "surprising implications" for the dissemination of culture and even the future of classical music.[270]

In May 2014, before Music Key service was launched, the independent music trade organization Worldwide Independent Network alleged that YouTube was using non-negotiable contracts with independent labels that were "undervalued" in comparison to other streaming services, and that YouTube would block all music content from labels who do not reach a deal to be included on the paid service. In a statement to the Financial Times in June 2014, Robert Kyncl confirmed that YouTube would block the content of labels who do not negotiate deals to be included in the paid service "to ensure that all content on the platform is governed by its new contractual terms." Stating that 90% of labels had reached deals, he went on to say that "while we wish that we had [a] 100% success rate, we understand that is not likely an achievable goal and therefore it is our responsibility to our users and the industry to launch the enhanced music experience."[215][216][217][218] The Financial Times later reported that YouTube had reached an aggregate deal with Merlin Network—a trade group representing over 20,000 independent labels, for their inclusion in the service. However, YouTube itself has not confirmed the deal.[209]
In April 2013, it was reported that Universal Music Group and YouTube have a contractual agreement that prevents content blocked on YouTube by a request from UMG from being restored, even if the uploader of the video files a DMCA counter-notice. When a dispute occurs, the uploader of the video has to contact UMG.[330][331] YouTube's owner Google announced in November 2015 that they would help cover the legal cost in select cases where they believe fair use defenses apply.[332]
Google does not provide detailed figures for YouTube's running costs, and YouTube's revenues in 2007 were noted as "not material" in a regulatory filing.[279] In June 2008, a Forbes magazine article projected the 2008 revenue at $200 million, noting progress in advertising sales.[280] In January 2012, it was estimated that visitors to YouTube spent an average of 15 minutes a day on the site, in contrast to the four or five hours a day spent by a typical US citizen watching television.[28] In 2012, YouTube's revenue from its ads program was estimated at $3.7 billion.[281] In 2013 it nearly doubled and estimated to hit $5.6 billion according to eMarketer,[281][282][283] while others estimated $4.7 billion.[281] The vast majority of videos on YouTube are free to view and supported by advertising.[56] In May 2013, YouTube introduced a trial scheme of 53 subscription channels with prices ranging from $0.99 to $6.99 a month.[284] The move was seen as an attempt to compete with other providers of online subscription services such as Netflix and Hulu.[56] In 2017, viewers on average watch YouTube on mobile devices for more than an hour every day.[285]
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.
