Pinterest is a pinboard-style social photo sharing website that allows users to create and manage theme-based image collections such as events, interests, hobbies, and more. Users can browse other pinboards for inspiration, ‘re-pin’ images to their own collections or ‘like’ photos. Pinterest’s mission is to “connect everyone in the world through the ‘things’ they find interesting” via a global platform of inspiration and idea sharing. Founded by Ben Silbermann (of West Des Moines, Iowa), Paul Sciarra, and Evan Sharp the site is managed by Cold Brew Labs and funded by a small group of entrepreneurs and inventors.
Pinterest is similar to earlier social, image bookmarking systems based on the same principle, such as David Galbraith’s 2005 project Wists. It allows users to save images and categorize them on different boards. They can follow other users’ boards if they have similar tastes. Popular categories are travel, cars, film, humor, home design, sports, fashion, and art.
Development of Pinterest began in December 2009, and the site launched as a open beta.
Silbermann said he personally wrote to the site’s first 5,000 users offering his personal phone number and even meeting with some of its users.
Nine months after launch the website had 10,000 users. Silbermann and a few programmers operated the site out of a small apartment until the summer of 2011.
Early in 2010, the company’s investors and co-founder Ben Silbermann tried to interest a New York-based magazine publishing company in buying Pinterest. The publisher declined to meet with the founders.
The launch of an iPhone app in early March 2011 brought in a more than expected number of downloads.

On 10 August 2012, Pinterest was opened to everyone without request or require an invitation.
On September 20, 2012 Pinterest announced that it has hired its new head of engineering, Jon Jenkins. Jenkins came from Amazon, where he spent eight years as an engineering lead and was also a director of develop tools, director of platform analysis and director of website platform.
In October of 2012, Pinterest announced a new feature that would allow users to report others for negative and offensive activity or block other users if they do not want to view their content. Pinterest said they want to keep their community “positive and respectful.”.
Pinterest users can upload, save, sort and manage images, known as pins, and other media content (i.e. videos) through collections known as pinboards. or be implemented by a webmaster directly on the website.
There are several ways to register a new Pinterest account. Potential users can either receive an invitation from a friend already registered, or request an invitation directly from the Pinterest website. The invitation may take some time to be received. An account can also be created and accessed by linking Pinterest to a 
On the main Pinterest page, a “pin feed” appears, displaying the chronological activity from the pinterest boards that a user follows. For both guests and Pinterest users, there are currently four main sections to browse: everything, videos, popular, and gifts. These subcategories provide an organized system of browsing, which helps fellow users to connect and share interests.
Quick links to Pinterest include the “pin it” button that can be added to the bookmark bar of a web browser, “Follow me” and “Pin it” buttons added to personal website or blog page,
Users should be aware of certain terms and functions when using Pinterest. A “board” is where the users pins are located, users can have several boards for various items. A “pin” is an image that has either been uploaded or from a link on a website. Once users create boards and add pins, other users can now “repin” meaning that they can “pin” one users image to their board as well. Once the user has set up their account and boards, they can browse, comment, and like other “pins”. If a user wants to turn an image online into a “pin” there are a few simple steps to do so. First, the user must elect image that you want to pin. Second, user then click on the “Add +” button on Pinterest. Third, copy & paste image URL into link box. Next, the user will select the exact image they wish to pin and place in designated board. Users can then describe the pin and share via Twitter or Facebook. Other users can now click on the pin to see which board the image is pinned in, who pinned the image previously, where the original pin is from, and who has liked, commented, or repinned the image.
The website has proven especially popular among women.
Pinboards can be used by educators to plan lessons. Teachers can pin sites for later referral. Students can pin and organize sources and collaborate on projects.
Pinterest has played a role in the run-up to the 2012 US Presidential Election. The wives of both candidates created accounts. Ann Romney debuted her Pinterest account in March and First Lady Michele Obama announced hers in June.

The site has been popular with American women and, in 2012, it was reported that 83% of the U.S. users were women.[

Pinterest was first conceptualized in December 2009 by co-founders Ben Silbermann, Evan Sharp and Paul Sciarra. The first prototype was launched in March 2010 where it was available to a small group of colleagues and family members. Since its inception three years ago, it has developed into a well-funded site financially supported by a group of successful entrepreneurs and investors including: FirstMark Capital, Jack Abraham (Milo), Michael Birch (Bebo), Scott Belsky (Behance), Shana Fisher (Highline Venture Partners), Ron Conway (SV Angel), Kevin Hartz (EventBrite), Jeremy Stoppelman (Yelp), Hank Vigil, Fritz Lanman, and Brian S. Cohen”. As Pinterest continues to grow and develop, so does its business opportunity as a promising marketing platform, especially in terms of data collection for retail companies and marketing strategists.
In early 2011, the company secured a $10 million USD Series A financing led by Jeremy Levine and Sarah Tavel of Bessemer Venture Partners. In October 2011, after an introduction from Kevin Hartz and Jeremy Stoppelman, the company secured $27 million USD in funding from Andreessen Horowitz, which valued the company at $200 million USD.
Retail companies have taken advantage of Pinterest for advertising and style trending. The web design provides an ideal layout for “style conscious retailers”,
Baynote founder Scott Brave sees Pinterest as an ideal environment to collect affinity data; a resource that holds the potential for substantial demand and income. This data “reveals valuable relationships between consumer behaviours, products and content”, where it can be collected and sold as marketing analysis.
 Copyrighted content
Pinterest has a notification system which allows copyright holders to request that content be removed from the site. The Digital Millennium Copyright Act (DMCA) safe harbor status of Pinterest has been questioned given that it actively promotes its users to copy to Pinterest, for their perpetual use, any image on the internet. Pinterest users cannot claim safe harbor status and as such are exposed to possible legal action for pinning copyrighted material.
A “nopin” HTML meta tag was released by Pinterest on 20 February 2012 to allow websites to opt out of their images being pinned. On 24 February 2012, Flickr implemented the code to allow users to opt out their photos.
Pinterest released a statement in March 2012 saying it believed it was protected by the DMCA’s safe harbor provisions.
In early May 2012, the site added automatic attribution of authors on images originating from Flickr, Behance, YouTube and Vimeo. Automatic attribution was also added for Pins from sites mirroring content on Flickr. At the same time Flickr added a Pin shortcut to its share option menu to users who have not opted out of sharing their images.
 Terms of service
A terms of service have been garnering a lot of criticism for stating in no uncertain terms that anything you “pin” to their site belongs to them. Completely. Wholly. Forever and for always”.
Pinterest’s Terms of Service stated:
“By making available any Member Content through the Site, Application or Services, you hereby grant to Cold Brew Labs a worldwide, irrevocable, perpetual, non-exclusive, transferable, royalty-free license, with the right to sublicense, to use, copy, adapt, modify, distribute, license, sell, transfer, publicly display, publicly perform, transmit, stream, broadcast, access, view, and otherwise exploit such Member Content only on, through or by means of the Site, Application or Services”.
Under the terms all personal, creative and intellectual property posted to the site belonged to the website and could be sold.
The fact that the content could be sold particularly unsettled another Scientific American blogger who said, “Problematically in the same paragraph, Pinterest states: ‘Cold Brew Labs does not claim any ownership rights in any such Member Content’. So which is it? Do they claim ownership to the content or not? And what are they planning to sell, anyway?”
In March 2012, Pinterest unveiled updated terms of service that ended the site’s claims of ownership once implemented in April. “Selling content was never our intention”, said the company in a blog post.
 Legal status
In February 2012, photographer and lawyer Kirsten Kowalski wrote a blog post explaining how her interpretation of copyright law led her to delete all her infringing pins.
Content creators on sites such as Getty Images said that it was aware of Pinterest’s copyright issues and was in discussion with them.
 Third party developers and content
Many third party developers have created web-apps, browser extensions, and even podcasts devoted to Pinterest. These items range from analytics, to enlarging the images on Pinterest’s website.
 Use by scammers
Social engineering of Pinterest users by scammers to propagate surveys promising free products was noted by the computer security firm Symantec in March 2012. Scam images, often branded with a well-known company name like Starbucks, offer incentives such as gift cards for completing a survey. Once the link in the description is clicked, users are taken to an external site and asked to re-pin the scam image. Victims are phished for their personal information and the promised free product is never delivered.
Other scammers capitalized on the lack of an official Google Play app. Low-quality Pinterest apps purporting to be official have appeared that generate ad revenue or monitor the downloader’s activity. There is now an official Pinterest app for Android devices.
