Google.
Google was started by two graduate students as Standford University. Larry Page and Sergey Brin were studying for their Ph.D. degrees when they started on the project that turned into google! Page and Brin believed that the pages with the most links from other important site on the internet are likely to be the most relevant to the person conducting the search. At first, the men conducted their studies on campus, but eventually they moved off campus and officially incorporated their company from a friend’s garage in Menlo Park, California. Today, millions of users visit google.com daily to search the internet and are drawn by its simple and easy-to-use design and the fact that the site is free. Google makes its money through advertising. Google sells advertising by the popularity of a keyword and not just banner ads that are so popular on other websites like YouTube or Facebook. Larry and Sergey never finished graduate school, but they are now two of the most famous men in Silicon Valley – the home of many technology start-up companies.

youtube

YouTube was founded by Chad Hurley, Steve Chen and Jawed Karim, who were all early employees of PayPal.[1] Prior to PayPal, Hurley studied design at Indiana University of Pennsylvania. Chen and Karim studied computer science together at the University of Illinois at Urbana-Champaign.[2] The domain name "YouTube.com" was activated on February 15, 2005,[3] and the website was developed over the subsequent months. The creators offered the public a preview of the site in May 2005, six months before YouTube made its official debut. Like many technology startups, YouTube was started as an angel-funded enterprise from a makeshift office in a garage. In November 2005, venture firm Sequoia Capital invested an initial $3.5 million;[4] additionally, Roelof Botha, partner of the firm and former CFO of PayPal, joined the YouTube board of directors. In April 2006, Sequoia put an additional $8 million into the company, which had experienced huge popular growth within its first few months.[5]

During the summer of 2006, YouTube was one of the fastest growing websites on the Web,[6] and was ranked the 5th most popular website on Alexa, far out pacing even MySpace's rate of growth.[7] According to a July 16, 2006 survey, 100 million video clips are viewed daily on YouTube, with an additional 65,000 new videos uploaded every 24 hours. The website averages nearly 20 million visitors per month, according to Nielsen/NetRatings,[8] where around 44% are female, 56% male, and the 12- to 17-year-old age group is dominant.[9] YouTube's pre-eminence in the online video market is substantial. According to the website Hitwise.com, YouTube commands up to 64% of the UK online video market.[10]

On October 9, 2006, it was announced that the company would be purchased by Google for US$1.65 billion in stock. The purchase agreement between Google and YouTube came after YouTube presented three agreements with media companies in an attempt to escape the threat of copyright-infringement lawsuits. YouTube will continue operating independently, with its co-founders and 67 employees working within the company.[11] The deal to acquire YouTube closed on November 13, and was, at the time, Google's second largest acquisition.[12] Google’s February 7th, 2007 SEC filing revealed the breakdown of profits for YouTube’s investors after the sale to Google. At the time of reporting Sequoia Capital’s shares were valued at more than $442 million, Chad Hurley’s at more than $345 million, Steve Chen’s at more than $326 million, and Jawed Karim’s at more than $64 million.[13]
