The 9gag website is based in Hong Kong, but it is hosted in the United States. It came out in 2008. Most of the site's content is just repeated versions of popular memes, most of which are rage comics. The site lets people share images in the same way that 4chan, reddit, and Funnyjunk do. However, people can post using their Facebook accounts, and each post has a "like" button, just like on reddit and Funnyjunk. People on the Internet know about 9gag because it is said to steal content from other sites. It is also known for being a scapegoat for /b/ and Anonymous's many misdeeds, just like Ebaumsworld.
In 2008, five Hong Kongers—University of Hong Kong student Ray Chan, his brother Chris Chan, Derek Chan, Marco Fung, and Brian Yu—got together to start the website. They wanted to make an online alternative to email where people could easily share funny photos or videos. In an interview in 2012, CEO Ray Chan refused to say where the name "9GAG" came from.
The co-founders of 9GAG started the company with the idea that it was "Just for Fun." They then used 9GAG to build their resumes for the 500 Startups accelerator program. The 9GAG team worked on other startup ideas like StartupQuote and Songboard during the summer program. After the 500 Startups accelerator program, 9GAG joined Y Combinator's incubator, where its number of users grew to 70 million unique visitors per month from all over the world. The people who helped start 9GAG stopped working on any other projects and put all of their efforts into 9GAG. 500 Startups was given stock in exchange for their help and advice.
In July 2012, venture capital firms in Silicon Valley, such as True Ventures and Greycroft Partners, gave 9GAG an extra $2.8 million. In August 2012, True Ventures, Greycroft Partners, and other Silicon Valley venture capitalists, as well as individual investors like Christopher Sacca, Kevin Rose, and Naval Ravikant, gave 9GAG another $2.8 million. With this money, 9GAG's engineering team was able to grow in both Hong Kong and Silicon Valley. The main office of 9GAG is in Mountain View, California, but the company is based in Tsuen Wan, Hong Kong.
Mobile app development
iOS, Android, Windows Phone 8, and BlackBerry 10 all have apps for 9GAG.
9GAG released an app for iOS and Android in July 2012. The mobile app is a streamlined version of the content on the website.  9GAG released 9CHAT in the summer of 2014. Users can log in to their 9GAG account and send a message to someone else to write to them. 9CHAT also added the ability to make groups in different places.  9GAG's first game, 9GAG Redhead redemption, came out in January 2015.
Content and who wrote it
Users and admins of 9GAG can also re-post content from other sites (like 4chan, Newgrounds, Reddit, SomethingAwful, FunnyJunk, YTMND, Instagram, etc.) with their own watermarks instead of the watermarks from the original sites. In 2011, 9GAG and 4chan fought over who made internet memes that were posted on both sites. Each site said the memes came from their own site. Ray Chan said, "9GAG doesn't make memes or rage comics; it just helps them get around." In 2015, Amanda Hess wrote in Slate that 9GAG's reposting of Instagram content was part of a "online ecosystem of joke stealing."
Albin Wagener, a linguist, looked at 446 posts on 9GAG's main page for his 2014 article "Building Identity and Building Bridges Between Cultures: The Case of 9gag." Of these, 40 (8.97%) were clearly racist. Most of the posts that were unfair to women were misogynistic (57.5%), then they were racist (25%), and then they were homophobic (12.5%). Wagener says that 9GAG brings people together around the world, but it does so by using masculine and heterosexual symbols and putting down other groups.
