The cat is a small, usually furry, domesticated, carnivorous mammal that is valued by humans for its companionship and for its ability to hunt vermin and household pests. It is currently the most popular pet in the world. Images and videos of cats are widespread on the Internet, including Tumblr , DeviantArt , Reddit  and many other places on the internet. The New York Times  and Thought Catalog  have reported on the cats’ fame on the internet.
PIctures of cats have been shared online as early as since the days of Usenet through newsgroups like rec.pets.cats, which offered a variety of answers to general questions people have about raising cats. The group’s FAQs were originally written in 1992 and released online in four parts over the span of nearly three years. In the late 1990s and early 2000s, the introduction of personal blogging and consumer-grade digital cameras charted a new era of animal photo blogs across the world, particularly in Japan where cats are generally considered the most favored pet animal. Daily photo and video journals of domesticated cats soon became a staple genre of blogging on the Japanese web, compounded by the advents of leaderboard-style blog ranking sites, as well as technological innovations in digital cameras and video recorders.
In the English-speaking online communities, pictures of cats became a recurring topic on memetic hubs like the B3TA Forum, Metafilter, General Mayhem, Something Awful, 4chan and FARK, just to name a few. Pictures of cats were also spread through chain e-mail networks, the most notable pre-LOLcat example being “Everytime you masturbate, God kills a kitten” (shown below, right). Some of the early adopters in the blog world include MyCatHatesYou, a single topic blog dedicated to cat photos since 2000, Rathergood, an internet culture site launched by B3ta forum member Joel Veitch in 2000, and the Infinite Cat Project, a blog that curates pictures of cats looking at another cat, that began in 2004.
However, the online popularity of cat-related media took a leap forward beginning in 2006 with the growing influence of LOLcats and Caturday on Something Awful and 4chan as well as the launch of YouTube, which essentially paved the way for the ubiquitous, multimedia presence of cats. The LOLcat phenomenon is thought to have entered the mainstream of the Internet sometime after the launch of I Can Has Cheezburger in early 2007.
As of 2012, cats continue to remain culturally influential and relevant on some of the largest media-sharing communities and publishing networks on the web such as YouTube, Tumblr, Reddit and Cheezburger. The increasing presence of cat-related media on YouTube and elsewhere on the web have been noted by various news publications: Salon’s article “The Internet is Made of Cats” and TIME Magazine’s article “A Day Without Cats on the Internet” in 2009, Mashable’s article “Why does the web love cats?” and BBC’s article “Cute cats, memes and understanding the internet” in 2012, among many others. In addition, numerous academic research projects have been initiated around the peculiar subject.
Caturday is the tradition of posting LOLcats to 4chan on Saturdays. It has since spread to other websites as well as other days of the week. Caturday originated on 4chan in the mid-2000s. Urban Dictionary’s earliest definition was added on October 24th, 2006.

On June 12th, 2012, a group of Google researcher led by the Standford University computer scientist Andrew Ng and the Google fellow Jeff Dean published the findings of its years-long study on the simulation of the human brain in a paper titled “Building High-level Features Using Large Scale Unsupervised Learning.” At the heart of the research project is an artificial neural network created by connecting 16,000 processors with more than one billion connections, which was then put to exposure of thumbnails extracted from at least 10 million YouTube videos.

Affirming the popular myth that “YouTube is made of cat videos,” the study revealed that Google’s neural network model was able to teach itself to recognize cats--along with human faces and bodies--far better than others in a list of 20,000 distinct items or objects. The research findings were picked up by numerous news sites and tech blogs, beginning with the New York Times’ article “How Many Computers to Identify a Cat? 16,000” published on June 26th, 2012.
Internet Cat Video Film Festival
In late May 2012, blogger Katie Czarniecki announced that she will be hosting a film festival dedicated to online videos of cats at the Walker Art Center, a reputable modern museum art located in Minneapolis, Minnesota.
