YouTube is an American online video-sharing platform headquartered in San Bruno, California. The service, created in February 2005 by three former PayPal employees—Chad HurleySteve Chen, and Jawed Karim—was bought by Google in November 2006 for US$1.65 billion and now operates as one of the company’s subsidiaries. YouTube is the second most-visited website after Google Search, according to Alexa Internet rankings.[7]

YouTube allows users to upload, view, rate, share, add to playlists, report, comment on videos, and subscribe to other users. Available content includes video clipsTV show clips, music videosshort and documentary films, audio recordings, movie trailerslive streamsvideo blogging, short original videos, and educational videos. Most content is generated and uploaded by individuals, but media corporations including CBS, the BBCVevo, and Hulu offer some of their material via YouTube as part of the YouTube partnership program. Unregistered users can watch, but not upload, videos on the site, while registered users can upload an unlimited number of videos and add comments. Age-restricted videos are available only to registered users affirming themselves to be at least 18 years old.

As of May 2019, there were more than 500 hours of content uploaded to YouTube each minute and one billion hours of content being watched on YouTube every day.[8] YouTube and selected creators earn advertising revenue from Google AdSense, a program that targets ads according to site content and audience. The vast majority of videos are free to view, but there are exceptions, including subscription-based premium channels, film rentals, as well as YouTube Music and YouTube Premium, subscription services respectively offering premium and ad-free music streaming, and ad-free access to all content, including exclusive content commissioned from notable personalities. Based on reported quarterly advertising revenue, YouTube is estimated to have US$15 billion in annual revenues.

GCP History

Google – 1998 AD

Return to Timeline of the History of Computers

1998

Google

Larry Page (b. 1973), Sergey Brin (b. 1973)

“The seed for what would become Google started with Stanford graduate student Larry Page’s curiosity about the organization of pages on the World Wide Web. Web links famously point forward. Page wanted to be able to go in the other direction.

To go backward, Page built a web crawler to scan the internet and organize all the links, named BackRub for the backlinks it sought to map out. He also recognized that being able to qualify the importance of the links would be of great use as well. Sergey Brin, a fellow graduate student, joined Page on the project, and they soon developed an algorithm that would not only identify and count the links to a page but also rank their importance based on quality of the pages from where the links originated. Soon thereafter, they gave their tool a search interface and a ranking algorithm, which they called PageRank. The effort eventually evolved into a full-blown business in 1998, with revenue coming primarily from advertisers who bid to show advertisements on search result pages.

In the following years, Google acquired a multitude of companies, including a video-streaming service called YouTube, an online advertising giant called DoubleClick, and cell phone maker Motorola, growing into an entire ecosystem of offerings providing email, navigation, social networking, video chat, photo organization, and a hardware division with its own smartphone. Recent research has focused on deep learning and AI (DeepMind), gearing up for the tech industry’s next battle—not over speed, but intelligence.

Merriam-Webster’s Collegiate Dictionary and the Oxford English Dictionary both added the word Google as a verb in 2006, meaning to search for something online using the Google search engine. At Google’s request, the definitions refer explicitly to the use of the Google engine, rather than the generic use of the word to describe any internet search.

On October 2, 2015, Google created a parent company to function as an umbrella over all its various subsidiaries. Called Alphabet Inc., the American multinational conglomerate is headquartered in Mountain View, California, and has more than 70,000 employees worldwide.”

Google’s self-described mission is to “organize the world’s information and make it universally accessible and useful.”
