The image that started everything was taken on June 12, 2002, with a Sony Cyber-shot camera during the renovation of a former furniture store at 807-811 Oregon Street in Oshkosh, Wisconsin4. The building, once home to Rohner's Home Furnishings, was being converted into a HobbyTown hobby shop with an RC car racing track called Revolution Racing5. One photograph from the renovation showed a large carpeted room with yellow wallpaper and fluorescent lighting, shot at a Dutch angle. The image was uploaded to the HobbyTown Oshkosh website on March 2, 2003, with the file name "Dsc00161.jpg" and captioned as "the original view of the East (Oval) room"5.

This photograph circulated on various message boards between 2011 and 2018 before landing on 4chan. On April 21, 2018, an anonymous user posted the image on /x/ (4chan's paranormal board) in a cursed images thread3. Then on May 12, 2019, a different anonymous user started a new /x/ thread asking people to "post disquieting images that just feel 'off'" and included the same photograph4. Another user replied with the text that would define the entire concept:

> "If you're not careful and you noclip out of reality in the wrong areas, you'll end up in the Backrooms, where it's nothing but the stink of old moist carpet, the madness of mono-yellow, the endless background noise of fluorescent lights at maximum hum-buzz, and approximately six hundred million square miles of randomly segmented empty rooms to be trapped in. God save you if you hear something wandering around nearby, because it sure as hell has heard you."2

That single paragraph, just 75 words, launched an entire genre.

The Backrooms moved from 4chan in-joke to mainstream cultural touchstone faster than most creepypastas. The A24 film adaptation, directed by the teenager whose YouTube series popularized the concept, represents one of the clearest pipelines from internet folklore to Hollywood production in recent years2. Dan Erickson naming The Backrooms as an influence on Severance shows its reach into prestige television4.

The concept's influence on the broader liminal space aesthetic is significant. While the question of whether The Backrooms invented or merely popularized liminal horror is debated, the creepypasta gave the movement its most recognizable visual language4. The #liminalspaces hashtag's nearly 100 million TikTok views are largely downstream of The Backrooms' cultural footprint4.

Tama Leaver, professor of internet studies at Curtin University, noted that the "eerie feeling of familiarity" is what draws fans together4. The Backrooms proved that horror doesn't need explicit threats. Sometimes an empty room with bad carpet is enough.

The Backrooms didn't appear out of nowhere. The underlying aesthetic of empty, unsettling spaces had been building on the internet for years. Musée Magazine traced the cult following of liminal space photography back to a broader movement on Reddit, where over 170,000 people shared and discussed images of eerily vacant places1. The magazine connected these spaces to architecture's emotional power, arguing that corridors, empty malls, and transition zones tap into "the basic human condition of ephemerality"1. The Backrooms gave this diffuse aesthetic a name, a mythology, and a narrative framework.

The collaborative fiction aspect is what set The Backrooms apart from other creepypastas. ABC News and Le Monde grouped it alongside the SCP Foundation as part of an "emerging genre of collaborative online horror"4. Unlike fan communities built around existing properties, The Backrooms had no original author asserting control over canon. This made it both creatively fertile and chaotic. As ABC News noted, the lack of a single canonical Backrooms made "drawing a line between authentic storytelling and jokes" difficult4. Kotaku observed that the horror worked precisely because of what it didn't show, inviting viewers to fill in the blanks4.

The biggest single boost to the concept came in January 2022 when Kane Parsons, a high school student posting under the name Kane Pixels, uploaded a found footage short film to YouTube2. The video depicted someone stumbling into the Backrooms through a glitch in reality, filmed in a retro VHS style with impressive CGI environments. It went viral well beyond the existing creepypasta community4. Parsons didn't stop at one video. He built out his own mythology involving an organization called Async that studies the Backrooms Complex, creating a serialized narrative that drew millions of viewers2.

The quality of Parsons' work attracted Hollywood attention. On February 6, 2023, it was announced that Parsons would direct a feature film adaptation produced by A243. He wisely finished high school before committing to the project2. The film stars Chiwetel Ejiofor and Renate Reinsve2. Dan Erickson, creator of the Apple TV+ series Severance, cited The Backrooms as one of his influences4.

One long-standing mystery was the origin of the photograph itself. For years, nobody knew where it was taken. In May 2024, a Twitter/X user named @tjxz_z posted that their friend had discovered the source, a claim that pulled over 8,200 reposts and 81,800 likes in a single day3. The discovery was actually the result of a coordinated effort within a Backrooms Discord community, which traced the image through the Wayback Machine to an archived webpage from March 20034. The room turned out to be the second floor of a former furniture store in Oshkosh, Wisconsin, photographed during its conversion into an RC car racing facility5. The blog post described extensive water damage that required gutting the space, which explained the bare, unsettling appearance5. The room's original layout is long gone, with HobbyTown having since converted the space into Revolution Racing4.

Critics and academics have connected The Backrooms to a longer tradition of architectural horror. Paste magazine's Phoenix Simms linked it to the color yellow as a symbol of caution, deterioration, and existential distress, describing the Backrooms' palette as "a fungal, sickly yellow"4. PC Gamer compared the various levels to H.P. Lovecraft's R'lyeh and the manga Blame!, calling it "an uncanny valley of place"4. The connection to Mark Z. Danielewski's novel House of Leaves, about a house that is larger on the inside than the outside, is frequently cited as a literary predecessor2.

The concept also spawned offshoot memes. The McDonald's Backrooms recontextualized the idea by placing it inside abandoned or retro fast-food restaurants, combining corporate nostalgia with existential dread6. TikTok creators built out variations using eerie audio filters and found footage of empty PlayPlaces6. Multiple video games based on the concept were released, and American Horror Stories produced an episode inspired by the lore2.
