Lotte World Busan opened a horror attraction called Gwimun Radio on July 17, and it has no screen at all. Its partner was the YouTube channel Whatsup! Horror Radio. Seven channels built on that same idea — lights off, voice only — hold 7,529 hours of collected long-form video inside Dhesy's data, or 313 days of round-the-clock playback.
The week horror moved off the screen
Two weeks later, on July 31, the streaming service Wavve launched an audio mode called Deutpom. According to Herald Business, MBC's Midnight Horror Story Show and The Devil's Plan are offered as audio, and mystery and ghost-story YouTube programming was added to the lineup. On August 3, episode 7 of Midnight Horror Story Show season 6 airs.
Newsis described the Gwimun Radio partner channel as having roughly 4,200 videos and 260,000 subscribers; Dhesy's own count lands in the same place, at 4,241 collected videos and 262,000 subscribers. The channel describes itself as one host dubbing every part, adding narration and adaptation on top. Watching horror turned into listening to it, all in one week.
Why picking tonight's channel takes so long
Because recommendation lists hand you channel names but never tell you how many hours each one can actually fill. The seven channels here hold 3.253 million subscribers combined. Inside Dhesy's collected long-form data they add up to 7,529 hours — 313 days if you play them around the clock. Over the last 90 days, again within Dhesy's collected data, they uploaded 662 videos, 578 of them long-form.
What a recommendation list leaves out
Naver's Q&A boards repeat the same requests: "recommend a scary-story YouTuber," "help me find a scary-story video." A channel name answers half the question for someone who needs five straight hours before sleep.
Does the biggest catalog also play the longest
Count and runtime are different axes. Within Dhesy's collected data, the channel with the most long-form uploads is not the channel with the most hours.
How listeners who fall asleep to it choose
Korean blogs repeatedly describe these channels as background audio for sleeping, working, or cleaning. Choosing something to leave running in summer resembles how viewers pick armchair-travel channels, except nobody here needs to watch to the end.
Why the count leader and the runtime leader are different channels
Whatsup! Horror Radio leads with 3,932 hours. Horror Radio 0.4MHz Ssammui has the largest collected long-form catalog at 4,441 videos, yet ranks third by runtime with 936 hours. Its 16-minute short piece "Palcheok Gwisin," a retelling of the eight-foot ghost posted in August 2013, drew 1.735 million views — and more than 4,000 pieces of that size are what the catalog is made of.
| Channel | Subscribers | Collected long-form | Total runtime |
|---|---|---|---|
| Whatsup! Horror Radio | 262K | 4,066 | 3,932 h |
| Dolby Horror Radio | 1.2M | 1,404 | 1,323 h |
| Horror Radio 0.4MHz Ssammui | 327K | 4,441 | 936 h |
| Koviet TV | 137K | 1,455 | 536 h |
| Midnight Horror Story Show (MBC)* | 1.0M | 1,142 | 491 h |
| Goedeulnam Horror Stories | 202K | 536 | 196 h |
| Horror Department | 125K | 504 | 115 h |
| Seven-channel total | 3.253M | 13,548 | 7,529 h |

Two caveats belong with that table. These hours are the sum of videos Dhesy actually collected, so they sit below each channel's full catalog. And the starred row, MBC Mystery: Midnight Horror Story Show X Surprise, has only been collected since May 18, 2025 — it stays in the total but should be read out of any depth comparison. Which leaves the next question: how long is a single episode on the runtime leader?
Why the runtime leader has a 13-minute median
The top channel by runtime averages 58 minutes per long-form video but has a median of 13 minutes. Short pieces dominate the catalog while unedited live sessions running past three hours carry the total: an unedited session from August 31, 2017 runs 146 minutes, a 2019 abandoned-house episode runs 209 minutes, and the last 90 days include a 237-minute upload.
| Channel | Collected long-form | Average length | Median length |
|---|---|---|---|
| Whatsup! Horror Radio | 4,066 | 58 min | 13 min |
| Dolby Horror Radio | 1,404 | 57 min | 43 min |
| Seven-channel total / median | 13,548 | 22 min | 13 min |
Dolby Horror Radio is the mirror image. Across 1,404 collected long-form videos it averages 57 minutes with a 43-minute median, so almost any episode runs close to an hour. The format is a phone interview with a viewer about something they lived through, which makes one episode one story: its most-viewed video within Dhesy's collected data is a 37-minute prison story from a former gang member, at 3.92 million views. One channel accumulated hours through variance; the other through consistent episode length.
Channels where one episode fills an hour, and channels that stop at 12 minutes
Splitting the 578 long-form uploads of the last 90 days separates two types. Dolby's 108 uploads (52-minute median), Ssammui's 53 (41 minutes) and Whatsup!'s 52 (43 minutes) are binge-length. The MBC channel's 243 uploads (15 minutes), Koviet TV with 74 (12 minutes) and Horror Department with 36 (24 minutes) are made for short sittings.
| Channel | Long-form, last 90 days | Median length | Long-form hours | Avg. long-form views |
|---|---|---|---|---|
| Midnight Horror Story Show (MBC) | 243 | 15 min | 86 h | 59K |
| Dolby Horror Radio | 108 | 52 min | 143 h | 290K |
| Koviet TV | 74 | 12 min | 33 h | 14K |
| Horror Radio 0.4MHz Ssammui | 53 | 41 min | 39 h | 63K |
| Whatsup! Horror Radio | 52 | 43 min | 55 h | 20K |
| Horror Department | 36 | 24 min | 15 h | 20K |
| Goedeulnam Horror Stories | 12 | 16 min | 6 h | 32K |
| Seven-channel total / median | 578 | 24 min | 377 h | 32K |

The short-sitting side still programs long blocks. Koviet TV posted a 167-minute compilation within the last 90 days, and its most-viewed video within Dhesy's collected data is a 220-minute overnight random compilation with 2.38 million views. Horror Department runs the other way, with a seven-minute Noryangjin studio-apartment story (633,000 views) near the top, while the MBC channel's standout is a 42-minute re-cut of broadcast segments tied to the film Salmokji (1.72 million views). One type fills the night with a single episode; the other fills it with compilations. Which raises the next question: why do channels running formats this long barely post Shorts?
Averaging 250K views on Shorts, and stopping anyway
Five of the seven posted zero Shorts in the last 90 days. Dolby averaged 250,000 views across 151 Shorts and still stopped uploading them after February 28, 2025. Those Shorts carried the same title suffixes as the main episodes, so they were clips cut from full videos — what changed was the decision about how many clips a full episode is worth.
| Channel | Shorts to date | Last Shorts upload | Shorts, last 90 days |
|---|---|---|---|
| Midnight Horror Story Show (MBC) | 496 | 2026-07-31 | 80 |
| Whatsup! Horror Radio | 175 | 2026-05-10 | 4 |
| Dolby Horror Radio | 151 | 2025-02-28 | 0 |
| Koviet TV | 64 | 2026-04-17 | 0 |
| Horror Department | 14 | 2025-07-20 | 0 |
| Goedeulnam Horror Stories | 8 | 2025-01-07 | 0 |
| Horror Radio 0.4MHz Ssammui | 3 | 2026-04-10 | 0 |
| Seven-channel total | 911 | 2026-07-31 | 84 |
Ssammui has posted three Shorts since opening in 2013, Goedeulnam eight, and Horror Department stopped in July 2025 after 14 entries in its Ghost Encyclopedia series. Only the MBC channel produces Shorts continuously, and its 80 uploads are broadcast clips. When one story equals one episode, clipping stays optional.
When different channels tell the same story
Because several channels narrate the same source text. Ghost-story narration rests on a convention of asking amateur horror writers for permission first. A Korean blog notice about narration requests records how often creators asked to read translated stories on YouTube and elsewhere, and another blog states it publishes with permission from a writer on the Daum cafe "Hadron's Story Lodge." Whatsup! posted a 204-minute reading of the same source on June 6, 2026; Ssammui posted a 165-minute version on June 30.
A longer archive does not automatically mean a better channel. Goedeulnam Horror Stories holds 536 collected long-form videos and 196 hours, the shallowest catalog of the seven, yet its long-form videos averaged 32,000 views over the last 90 days — above Whatsup! (20,000), whose collected archive is twenty times deeper, and Koviet TV (14,000), nearly three times deeper. Its own most-played video is a 106-minute compilation of viewer-voted stories (988,000 views). Leaving something running and picking something to hear are separate demands, and the gap between subscriber size and view counts shows up in other genres too.
Where the narration went next, and what comes after August
The format has moved off YouTube in three directions. Dolby's novel The Red came out from arte in 2025 with 15 stories, seven in a shamanism section and eight about people; Seoul Economic Daily reported rising sales in an August 3, 2025 feature on summer mystery reading. Ssammui hosts the TV Chosun 2 mystery talk show Ghost Story Collector, which began on November 15, 2025 and, as of April 2026, airs Saturdays at 10:30 p.m. Whatsup! went physical through the Lotte World Busan attraction. Traffic runs the other way as well: on March 11, 2026, outlets reported that actors Kim Hye-yoon and Lee Jong-won would lend their voices to Dolby Horror Radio.
Broadcast follows the same structure. Midnight Horror Story Show season 6 airs Mondays at 10:50 p.m., pays 444,444 won per story featured, adds a bonus for the story voted first by its online audience, and brings in actor Keum Sae-rok for episode 7 on August 3. Reading viewer submissions and collecting reactions is the same loop the YouTube channels run.
Once the August search peak passes, the competition shifts from how many hours a channel has stacked up to how far outside YouTube it has traveled. Wavve's audio mode, the Lotte World Busan attraction, a cable hosting slot and a published book already point that way. More listening options also means the channel you pick this summer may reach you through a different window by autumn.
For tonight, it comes down to two choices. If one episode has to carry you to morning, Dolby's 52-minute median or Whatsup!'s 43 minutes fits; if you expect to wake up and pick again, Koviet TV's two- and three-hour compilations do.
Frequently asked questions
Where should someone start with Korean horror-story YouTube channels
For all-night listening, go by total runtime: Whatsup! Horror Radio at 3,932 hours, Dolby Horror Radio at 1,323 and Horror Radio 0.4MHz Ssammui at 936, all within Dhesy's collected long-form data. For one or two episodes, Koviet TV, the MBC channel and Horror Department run 12 to 24 minutes per video on median over the last 90 days.
What kind of channel is Dolby Horror Radio
It interviews viewers about true experiences and retells them. The channel has 1.2 million subscribers; all 108 uploads in the last 90 days were long-form with a 52-minute median, averaging 290,000 views. In March 2026, outlets reported that actors Kim Hye-yoon and Lee Jong-won would appear as voices.
Have the Dolby Horror Radio stories been published as a book
Host Dolby's novel The Red was published by arte in 2025, with seven shamanism stories and eight human-centered ones. Seoul Economic Daily noted rising sales in an August 3, 2025 article.
How do you find a horror-story video you heard a while ago
Narrow by catalog size first. Within Dhesy's collected data, Ssammui holds 4,441 long-form videos, Whatsup! 4,066, Koviet TV 1,455 and Dolby 1,404. These channels append the submitter's nickname and the channel name to titles, so searching a remembered word together with the channel name cuts the range quickly.
How do you choose a horror radio channel to fall asleep to
Look at episode length and compilation programming. Median lengths over the last 90 days run 52 minutes for Dolby, 43 for Whatsup! and 41 for Ssammui, so a playlist is optional. For compilations, Koviet TV posts two- and three-hour blocks, including a 220-minute set with 2.38 million views.
Methodology: Based on Dhesy platform data covering 6,912 brands and 64,165 creator channels. Video counts, runtimes and upload pace for the seven channels are limited to videos Dhesy has collected, and Shorts classification uses each video's stored Shorts flag. Period: 2026-05-03 – 2026-08-01 (KST, 90-day window); archive totals run from each channel's first collected video through 2026-07-31. Data source: Dhesy Last updated: 2026-08-01
