LinkedIn is an American business and employment-oriented service that operates via websites and mobile apps. Founded on December 28, 2002, and launched on May 5, 2003, it is mainly used for professional networking, including employers posting jobs and job seekers posting their CVs. As of 2015, most of the company’s revenue came from selling access to information about its members to recruiters and sales professionals.
Since December 2016 it has been a wholly owned subsidiary of Microsoft.
The LinkedIn logo is a typical example of a web 2.0 logo with bold and executive typefaces. It features the website’s name – “Linked” and “in” – with a slight spacing in between the two words. The word “in” is enclosed in a blue square box.
The LinkedIn logo is undoubtedly one of the most popular and instantly recognizable logos on the internet.
While the blue color in the LinkedIn logo stands for approachability, excellence and grace of the website, the black depicts its power and prestige. The white color, on the other hand, represents purity, integrity and charm of LinkedIn.
