History: This social network soon came to the stock market and had an immediate impact. In October 2008, it had more than 25 million registered users, extending to companies in 150 different industries, although technology predominated.
On May 19, 2011 became the first US social network to put shares on the stock market, with an initial price of US $45. The acceptance of the social network by investors was such that their shares rose 109%, up to 94 dollars and their stock price reached 8900 million dollars on Wall Street.
In March 2013, it had more than 200 million registered users, of more than 200 countries, covering all the Fortune magazine companies of the 500 largest US companies. It is followed in a distant second by Viadeo.
On June 13, 2016, Microsoft announced the purchase of LinkedIn for 26.2 billion dollars.
Features: One of the purposes of this site is that registered users can maintain a list with contact information of people with whom they have some level of relationship, called Connection. Users can invite anyone (either a site user or not) to join the connection. However, if the guest selects "I do not know" or "Spam", this counts against the person inviting. If the person inviting gets many of these answers, the account may become restricted or closed.
Privacy Issues: Non-members can check whether or not the person is a member. Since August 2007, this feature can be disabled. Since October 2006, there is no automated way to remove yourself from LinkedIn. The official method is to contact technical support.
Sales to Microsoft: In an official statement on June 13, 2016, Microsoft said it paid out $196 a share to Linkedin, totaling $26.2 billion. According to the document, the social network "will maintain its brand, culture and independence", and its current CEO, Jeff Weiner, will be retained in the position, reporting directly to Satya Nadella, CEO of Microsoft. The purchase was unanimously approved by the Boards of Directors of both companies.
According to Microsoft, LinkedIn's growth pace and product diversification were essential to catch the attention of the creator of Windows. In figures presented by the company, the corporate social network has presented an average growth of 19% on year, with more than 433 million registered members.
In addition, there are 105 million unique visitors per month (a 9% growth on year), greater engagement in its mobile application, 60% of total hits and a 34% increase in page number views, 45 billion views in the last quarter. There was also a 101% increase in the number of active job ads with seven million vacancies.
