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.”
Turkey blocked access between 2008 and 2010 after controversy over videos deemed insulting to Mustafa Kemal Atatürk. 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. During the two and a half-year block of YouTube, the video-sharing website remained the eighth-most-accessed site in Turkey. In 2014, Turkey blocked the access for the second time, after "a high-level intelligence leak."
YouTube is pulling in plenty of dollars – 4 billion of them in 2014, up by a billion on 2013 – but it’s also spending it like there’s no tomorrow. People “familiar with its financials” told the Wall Street Journal this week that after forking out for original content and also the infrastructure to keep the whole shebang going, the company is just about breaking even.
YouTube has enabled people to more directly engage with government, such as in the CNN/YouTube presidential debates (2007) in which ordinary people submitted questions to U.S. presidential candidates via YouTube video, with a techPresident co-founder saying that Internet video was changing the political landscape. Describing the Arab Spring (2010– ), sociologist Philip N. Howard quoted an activist's succinct description that organizing the political unrest involved using "Facebook to schedule the protests, Twitter to coordinate, and YouTube to tell the world." In 2012, more than a third of the U.S. Senate introduced a resolution condemning Joseph Kony 16 days after the "Kony 2012" video was posted to YouTube, with resolution co-sponsor Senator Lindsey Graham remarking that the video "will do more to lead to (Kony's) demise than all other action combined."
