Maybe better or more refined solutions exist, but if the history of children’s television teaches us anything, it’s that the market alone will not generate the best outcomes for kids. Nor is the United States government likely to demand change, at least not without prompting. Heroes will have to emerge to push for change in the new YouTube’d world, just as they did in the early days of broadcast children’s TV. And not all of those heroes will come from the Western world. They’ll come from all over the globe, maybe even Chennai.
In December 2011, YouTube launched a new version of the site interface, with the video channels displayed in a central column on the home page, similar to the news feeds of social networking sites.[54] At the same time, a new version of the YouTube logo was introduced with a darker shade of red, the first change in design since October 2006.[55] In May 2013, YouTube launched a pilot program for content providers to offer premium, subscription-based channels within the platform.[56][57] In February 2014, Susan Wojcicki was appointed CEO of YouTube.[58] In November 2014, YouTube announced a subscription service known as "Music Key", which bundled ad-free streaming of music content on YouTube with the existing Google Play Music service.[59]
In October 2010, Hurley announced that he would be stepping down as chief executive officer of YouTube to take an advisory role, and that Salar Kamangar would take over as head of the company.[51] In April 2011, James Zern, a YouTube software engineer, revealed that 30% of videos accounted for 99% of views on the site.[52] In November 2011, the Google+ social networking site was integrated directly with YouTube and the Chrome web browser, allowing YouTube videos to be viewed from within the Google+ interface.[53]
The results reflect YouTube’s struggles to expand its core audience beyond teens and tweens. Many YouTube users treat the site as a video repository to be accessed from links or embedded video players posted elsewhere, rather than visiting daily. Google executives want them to turn on YouTube the way they turn on television, as a habit, where they can expect to find different “channels” of entertainment.
The world of YouTube is vastly different from the world of broadcast television. While broadcasters in the United States and abroad are bound by rules, and the threat of punishment for breaking those rules, far fewer such regulations apply to the creators of YouTube content, or to YouTube itself. YouTube’s default position is that no one under 13 is watching videos on its site—because that’s the minimum age allowed under its terms of service. In addition to its main site, however, the company has developed an app called YouTube Kids. Like normal YouTube, it plays videos, but the design and content are specifically made for parents and children. It’s very good. It draws on the expertise of well-established children’s-media companies. Parents can restrict their children’s viewing in a multitude of ways, such as allowing access only to content handpicked by PBS Kids. But here’s the problem: Just a small fraction of YouTube’s 1.9 billion monthly viewers use it. (YouTube Kids is not available in as many countries as normal YouTube is.)
But what about the cost of servers, bandwith etc? I think it might be in the range of  $750 million per year to as high as $1.5 Bn plus ( we will never know as Google never reveals cost of running youtube, and Google has invested heavily in this space ). I feel Youtube as a standalone business  MAY NOT be as profitable a biz as Search and might never be since barely 10% of its content is actually monetizable. But for Google, with $30 Billion revenues, Youtube losses( even if money lost is as high as say $500 million per year) is chump change considering the strategic advantage it gives visavis competition. (Microsoft online businesses lost way more last 10 years). Youtube subsidy by Google has created a monopoly which has effectively destroyed all independent video ad network business plans.
Chandar met me and led me into a massive conference room. In addition to being the CEO, he composes music for ChuChu. He’s the public face of the company and, at 39, a few years younger than the other four founders, who each hold an equal stake. He sent a young man to get me a coffee, and then we sat down together with his friend B. M. Krishnan, a former accountant and a ChuChu co-founder who is now the company’s chief creative officer.

How does a video streaming service with one billion active users per month and $4 billion in revenue not turn a profit? Ask YouTube, which couldn't break free from breaking even in 2014, according to a new report. Sources tell the Wall Street Journal that Google's video unit posted $4 billion in revenue last year, up from $3 billion in 2013, and that while the service accounted for 6 percent of Google's overall sales, it contributed nothing to earnings.
In 2013, the average cost per thousand (CPM) for YouTube was $7.60. CPM (cost per thousand) is an industry term that represents revenue per thousand views. In 2013, the average income for each YouTube content creator was $7.60 per every thousand views. A video with 500 views would have earned roughly $3.80. A video like Gangnam Style with a billion views would earn $7.8 million. Some videos earn a higher or lower than average rate depending on the video content. Videos containing copyrighted music do not earn revenue for the video creator, and some topics may not attract advertisers. Others have a strong draw from advertisers and drive up the CPM.
I don’t mean the kind of corruption that regularly sends lowlifes like Rod Blagojevich, the Democratic former governor of Illinois, to prison. Those abuses are nonpartisan and always with us. So is vote theft of the kind we’ve just seen in North Carolina—after all, the alleged fraudster employed by the Republican candidate for Congress hired himself out to Democrats in 2010.
Still, one of the main ways (or easiest) to earn money on YouTube is through YouTube running ads on your videos. Once you get a certain amount of views, you can connect your account to a Google AdSense account, which will allow you to start earning money on your videos, according to USA Today. In order to qualify, you reportedly now need (as of January 2018) 4,000 watch hours in the past 12 months, plus 1,000 subscribers to join the YouTube Partner Program (which will get you ads and therefore cash from your channel). 
In May 2011, 48 hours of new videos were uploaded to the site every minute,[23] which increased to 60 hours every minute in January 2012,[23] 100 hours every minute in May 2013,[24][25] 300 hours every minute in November 2014,[26] and 400 hours every minute in February 2017.[27] As of January 2012, the site had 800 million unique users a month.[28] It is estimated that in 2007 YouTube consumed as much bandwidth as the entire Internet in 2000.[29] According to third-party web analytics providers, Alexa and SimilarWeb, YouTube is the second-most visited website in the world, as of December 2016; SimilarWeb also lists YouTube as the top TV and video website globally, attracting more than 15 billion visitors per month.[1][30][31] In October 2006, YouTube moved to a new office in San Bruno, California.[32]
