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]

An independent test in 2009 uploaded multiple versions of the same song to YouTube, and concluded that while the system was "surprisingly resilient" in finding copyright violations in the audio tracks of videos, it was not infallible.[339] The use of Content ID to remove material automatically has led to controversy in some cases, as the videos have not been checked by a human for fair use.[340] If a YouTube user disagrees with a decision by Content ID, it is possible to fill in a form disputing the decision.[341] Prior to 2016, videos weren't monetized until the dispute was resolved. Since April 2016, videos continue to be monetized while the dispute is in progress, and the money goes to whoever won the dispute.[342] Should the uploader want to monetize the video again, they may remove the disputed audio in the "Video Manager".[343] YouTube has cited the effectiveness of Content ID as one of the reasons why the site's rules were modified in December 2010 to allow some users to upload videos of unlimited length.[344]
From the looks of things, YouTube's top-line growth hasn't been hurt much by worries among some companies -- for example, Cisco Systems (CSCO) , which just announced it's halting its YouTube ad spend -- about the running of their ads against content they find to be inappropriate. It also doesn't appear to have been hurt badly by YouTube's attempts to appease such advertisers by "demonetizing" videos that its algorithms deem unsuitable for running ads against, or the backlash such actions have sparked among affected content creators.
But even if you discount YouTube's multiples a bit to account for its profit uncertainty, you're still left with a very valuable business. At six times Mizuho's revenue estimate, YouTube would be worth $90 billion. At seven times, it would be worth $105 billion. And those valuation figures would rise a little more if one tacked on a slight premium (say, $5 billion or $10 billion) for the potential of YouTube's subscription businesses.
Also in November 2017, it was revealed in the media that many videos featuring children – often uploaded by the minors themselves, and showing innocent content – were attracting comments from pedophiles[376][377] and circulating on the dark web, with predators finding the videos by typing in certain keywords in Russian.[377] As a result of the controversy, which added to the concern about "Elsagate", several major advertisers whose ads had been running against such videos froze spending on YouTube.[378][369]
Where eyeballs go, money follows. “People giving up TV and getting video content through mobile devices is a huge trend, and brands are spending huge amounts to reach those audiences,” says Evan Asano, the CEO of MediaKix, an influencer marketing agency. “It’s a similar, if not bigger market for influencers than Instagram.” Another reason brands love YouTube is that its numbers are harder to fake. “You can buy views on YouTube, but it’s much more expensive than buying followers and likes on Instagram,” Asano says. “It’s pretty cost-prohibitive to drastically inflate a channel’s views on a consistent basis.”
At first, pretty much everybody agrees, television for kids was bad—dumb cartoons, cowboy shows, locally produced slop. There also wasn’t much of it, so kids often watched whatever adult programming was on TV. In the early 1950s, one teacher enumerated the changes she’d seen in her pupils since they had “got television”: “They have no sense of values, no feeling of wonder, no sustained interest. Their shallowness of thought and feeling is markedly apparent, and they display a lack of cooperation and inability to finish a task.” There were calls for action.
The outcry against PewDiePie’s recommendation of the channel was immediate, with media outlets and other YouTuber users citing it as an example of PewDiePie’s ongoing dalliance in alt-right culture. In response, PewDiePie released a follow-up video on December 11 in which he sarcastically described the incident as an “oopsie” and scoffed at the idea that he was promoting neo-Nazism by merely “recommending someone for their anime review.”
YouTube began as a venture capital-funded technology startup, primarily from an $11.5 million investment by Sequoia Capital and an $8 million investment from Artis Capital Management between November 2005 and April 2006.[11][12] YouTube's early headquarters were situated above a pizzeria and Japanese restaurant in San Mateo, California.[13] The domain name was activated on February 14, 2005, and the website was developed over the subsequent months.[14] The first YouTube video, titled Me at the zoo, shows co-founder Jawed Karim at the San Diego Zoo.[15] The video was uploaded on April 23, 2005, and can still be viewed on the site.[16] YouTube offered the public a beta test of the site in May 2005. The first video to reach one million views was a Nike advertisement featuring Ronaldinho in November 2005.[17][18] Following a $3.5 million investment from Sequoia Capital in November, the site launched officially on December 15, 2005, by which time the site was receiving 8 million views a day.[19][20] The site grew rapidly and, in July 2006, the company announced that more than 65,000 new videos were being uploaded every day, and that the site was receiving 100 million video views per day.[21] According to data published by market research company comScore, YouTube is the dominant provider of online video in the United States, with a market share of around 43% and more than 14 billion views of videos in May 2010.[22]
