For kids to have the best chance of learning from a video, Johnson told me, it must unfold slowly, the way a book does when it is read to a child. “Calmer, slower-paced videos with less distracting features are more effective for younger children,” she said. “This also allows the video to focus attention on the relevant visuals for the song, thus aiding in comprehension.”
National Geographic magazine has announced the winning entries in its annual photo competition. The grand-prize winner this year is Jassen Todorov, who will take home a $5,000 prize for his aerial image of thousands of recalled Volkswagen and Audi cars in the Mojave Desert. The contest organizers have shared with us the top winners and honorable mentions below, selected from a pool of  nearly 10,000 entries. Captions are written by the individual photographers and lightly edited for content.
Apply to join the YouTube Partner Program when you feel confident in the interest and following your videos have garnered. There is no set following numbers needed to become a partner, but YouTube must see that your videos have interest and are growing a following before you're accepted. Sometimes YouTube will contact you directly about becoming a partner, especially if your videos have gone viral quickly. If not, you can apply on the YouTube partner page by entering personal information, describing a marketing plan, and defining your video genre.
Observing that face-to-face communication of the type that online videos convey has been "fine-tuned by millions of years of evolution", TED curator Chris Anderson referred to several YouTube contributors and asserted that "what Gutenberg did for writing, online video can now do for face-to-face communication".[254] Anderson asserted that it's not far-fetched to say that online video will dramatically accelerate scientific advance, and that video contributors may be about to launch "the biggest learning cycle in human history."[254] In education, for example, the Khan Academy grew from YouTube video tutoring sessions for founder Salman Khan's cousin into what Forbes'  Michael Noer called "the largest school in the world", with technology poised to disrupt how people learn.[255] YouTube was awarded a 2008 George Foster Peabody Award,[256] the website being described as a Speakers' Corner that "both embodies and promotes democracy."[257] The Washington Post reported that a disproportionate share of YouTube's most subscribed channels feature minorities, contrasting with mainstream television in which the stars are largely white.[258] A Pew Research Center study reported the development of "visual journalism", in which citizen eyewitnesses and established news organizations share in content creation.[259] The study also concluded that YouTube was becoming an important platform by which people acquire news.[260]
After all, relatability is a YouTuber’s greatest asset — along with a willingness to keep plugging away. “If you’re passionate about it, you really increase your chances of success,” says Asano. “It’s a lot of work. To produce just one video, you need camera equipment, a computer to edit it on, and time. And if you’re just starting out, you’re not going to get paid for a while because you need to build your subscribers. Don’t do it because you think you’re going to make an easy buck, because it’s not.”

Not to put too fine a point on it, but this is almost precisely the problem that the rest of the media world finds itself in. Because quality is hard to measure, the numbers that exist are the ones that describe attention, not effect: views, watch time, completion rate, subscribers. YouTube uses those metrics, ostensibly objectively, when it recommends videos. But as Theodore Porter, the great historian of science and technology, put it in his book Trust in Numbers, “Quantification is a way of making decisions without seeming to decide.”


If streaming video followed the broadcast model, YouTube—in partnership with governments around the world—could also subsidize research into creating educational content specifically for YouTube, and into how best to deliver it to children. The company could invest in research to develop the best quantitative signals for educational programming, so it could recommend that programming to viewers its algorithm believes to be children. It could fund new educational programming, just as broadcasters have been required to do for decades. (“We are always looking for ways to build the educational content offering in the app in a way that’s really fun and engaging for kids,” Ducard said.)
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.
Like any good mogul, Fischbach is diversifying: In October, he cofounded an athleisure line, Cloak, with fellow list member Seán McLoughlin, better known as “Jacksepticeye” (No. 8, $16 million). The workout line includes $85 sweaters and $35 T-shirts. Even if they intend to exercise nothing more than their thumbs, fans have snapped the gear up: The presale items sold out in 48 hours. 
YouTube already offers advertisers the opportunity to withdraw from advertising on some videos – such as LGBTQ content or discussions of mental health – if it doesn’t sit well alongside a brand’s message. It was revealed last year that this can sometimes then lead to content being demonetised. In other words, the creator does not receive a share of ad revenue for that video.
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 www.youtube.com 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]
