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.

YouTube has focused on developing online personalities such as video game player PewDiePie, music video specialist Smosh and style guru Michelle Phan. Driving much of the traffic to YouTube, analysts say, are multichannel networks such as Fullscreen, Maker Studios, SonyBMG and Whistle Sports. Google has bought stakes in multichannel networks such as Vevo and Machinima, analysts say, to ensure their content stays on its website.
Libya blocked access on January 24, 2010, because of videos that featured demonstrations in the city of Benghazi by families of detainees who were killed in Abu Salim prison in 1996, and videos of family members of Libyan leader Muammar Gaddafi at parties. The blocking was criticized by Human Rights Watch.[425] In November 2011, after the Libyan Civil War, YouTube was once again allowed in Libya.[426]
Estimates for YouTube's annual revenue, nearly all of which still comes from ads, vary a fair amount. But many of the estimates are now above $10 billion. At different points, Bank of America and Mizuho forecast that YouTube would post 2017 revenue of $13 billion and $12 billion, respectively. And in February, Baird's Colin Sebastian estimated YouTube is doing around $15 billion in annual sales.
Additionally, in response to PewDiePie’s rec of the E;R channel, its owner described PewDiePie as producing “redpilled content.” And it’s easy to see why. Before declaring in 2017 that he would stop making Nazi jokes, PewDiePie made a whole lot of Nazi jokes. Even since then, he’s produced a long line of “satirical” videos and commentary that his alt-right followers have praised as examples of his “dropping redpills” on the rest of his fans.
On September 13, 2016, YouTube launched a public beta of Community, a social media-based feature that allows users to post text, images (including GIFs), live videos and others in a separate "Community" tab on their channel.[121] Prior to the release, several creators had been consulted to suggest tools Community could incorporate that they would find useful; these YouTubers included Vlogbrothers, AsapScience, Lilly Singh, The Game Theorists, Karmin, The Key of Awesome, The Kloons, Peter Hollens, Rosianna Halse Rojas, Sam Tsui, Threadbanger and Vsauce3.[122]
To be clear, it’s hard to make videos that very young children can learn from. (Johnson’s doctoral adviser, Georgene Troseth, was part of the team that demonstrated this.) Children under 2 struggle to translate the world of the screen to the one they see around them, with all its complexity and three-dimensionality. That’s why things like Baby Einstein have been debunked as educational tools. Most important for kids under 2 is rich interaction with humans and their actual environments. Older toddlers are the ones who can get something truly educational from videos, as opposed to just entertainment and the killing of time.
YouTube originally offered videos at only one quality level, displayed at a resolution of 320×240 pixels using the Sorenson Spark codec (a variant of H.263),[86][87] with mono MP3 audio.[88] In June 2007, YouTube added an option to watch videos in 3GP format on mobile phones.[89] In March 2008, a high-quality mode was added, which increased the resolution to 480×360 pixels.[90] In November 2008, 720p HD support was added. At the time of the 720p launch, the YouTube player was changed from a 4:3 aspect ratio to a widescreen 16:9.[91] With this new feature, YouTube began a switchover to H.264/MPEG-4 AVC as its default video compression format. In November 2009, 1080p HD support was added. In July 2010, YouTube announced that it had launched a range of videos in 4K format, which allows a resolution of up to 4096×3072 pixels.[92][93] In June 2015, support for 8K resolution was added, with the videos playing at 7680×4320 pixels.[94] In November 2016, support for HDR video was added which can be encoded with Hybrid Log-Gamma (HLG) or Perceptual Quantizer (PQ).[95] HDR video can be encoded with the Rec. 2020 color space.[96]
How many views does it take to make money on YouTube?  This is a common question asked and it really depends on who you ask.  You may have heard that you’ll make one dollar per thousand views or that it’s $1,000 per Million Views.  Some say it’s $5 per thousand views.  Well, we’re asking the wrong question.  We should be asking, “How much ENGAGEMENT does it take to make money on YouTube?”
Both In-Stream and Discovery are pay-per-view -- you pay YouTube a fixed rate for every view the ad receives -- and their return on investment (ROI) can be measured in Google AdWords. YouTube tallies one new "view" after 30 seconds of watching, or a click on the video as it's playing. If the video is less than 30 seconds, views are tallied from people who watch the entire ad.
Turkey blocked access between 2008 and 2010 after controversy over videos deemed insulting to Mustafa Kemal Atatürk.[406][407][408] In November 2010, a video of the Turkish politician Deniz Baykal caused the site to be blocked again briefly, and the site was threatened with a new shutdown if it did not remove the video.[409] During the two and a half-year block of YouTube, the video-sharing website remained the eighth-most-accessed site in Turkey.[410][411] In 2014, Turkey blocked the access for the second time, after "a high-level intelligence leak."[412][413][414]
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]
