Previously, viewing YouTube videos on a personal computer required the Adobe Flash Player plug-in to be installed in the browser.[70] In January 2010, YouTube launched an experimental version of the site that used the built-in multimedia capabilities of web browsers supporting the HTML5 standard.[71] This allowed videos to be viewed without requiring Adobe Flash Player or any other plug-in to be installed.[72][73] The YouTube site had a page that allowed supported browsers to opt into the HTML5 trial. Only browsers that supported HTML5 Video using the MP4 (with H.264 video) or WebM (with VP8 video) formats could play the videos, and not all videos on the site were available.[74][75]
There are over a million members of the YouTube Partner Program.[298] According to TubeMogul, in 2013 a pre-roll advertisement on YouTube (one that is shown before the video starts) cost advertisers on average $7.60 per 1000 views. Usually no more than half of eligible videos have a pre-roll advertisement, due to a lack of interested advertisers.[299]

Broadcasters snipe at the quality of YouTube's videos, aiming to hold on to TV advertising. Competing in subscription-based services vs. the likes of Netflix and Hulu would take big content investments. Not knowing YouTube's costs, margins or growth history will make it hard to gauge how it's meeting the challenges -- and the potential for a blow to its value to Alphabet, whose overall market capitalization approaches $500 billion. Alphabet stock closed Friday at 747.60, up 1.5%.
YouTube Go is an Android app aimed at making YouTube easier to access on mobile devices in emerging markets. It is distinct from the company's main Android app and allows videos to be downloaded and shared with other users. It also allows users to preview videos, share downloaded videos through Bluetooth, and offers more options for mobile data control and video resolution.[225]
According to ChuChu, its two largest markets are the United States and India, which together generate about one-third of its views. But each month, tens of millions of views also pour in from the U.K., Canada, Mexico, Australia, and all over Asia and Africa. Roughly 20 million times a day, a caretaker somewhere on Earth fires up YouTube and plays a ChuChu video. What began as a lark has grown into something very, very big, inflating the company’s ambitions. “We want to be the next Disney,” Chandar told me.
In December 2012, two billion views were removed from the view counts of Universal and Sony music videos on YouTube, prompting a claim by The Daily Dot that the views had been deleted due to a violation of the site's terms of service, which ban the use of automated processes to inflate view counts. This was disputed by Billboard, which said that the two billion views had been moved to Vevo, since the videos were no longer active on YouTube.[393][394] On August 5, 2015, YouTube removed the feature which caused a video's view count to freeze at "301" (later "301+") until the actual count was verified to prevent view count fraud.[395] YouTube view counts once again updated in real time.[396]
It's a little awkward, so we'll get straight to the point: This Sunday we humbly ask you to defend Wikipedia's independence. We depend on donations averaging about $16.36. But 98% of our readers in the U.S. are not responding to our messages, and time is running out to help in 2018. If everyone reading this gave $2.75, we could keep Wikipedia thriving for years to come. The price of your Sunday coffee is all we need. When we made Wikipedia a non-profit, people warned us we'd regret it. But if Wikipedia were commercial, it would be a great loss. Wikipedia unites all of us who love knowledge: contributors, readers and the donors who keep us thriving. The heart and soul of Wikipedia is a community of people working to bring you unlimited access to reliable information. Please take a minute to help us keep Wikipedia growing. Thank you.
