Knowing Bros Keeps Its Saturday 9 p.m. Slot After Passing 500 Episodes
JTBC's long-running variety show Knowing Bros remains a Saturday-night platform for guest promotion, clips and fandom reach.
JTBC's variety show Knowing Bros is continuing in its Saturday 9 p.m. time slot even after moving beyond the 500-episode mark. The program, which first aired in December 2015, remains on the schedule as of June 2026, even as talk around the show now includes references to viewership ratings in the 1 percent range.

Even under that pressure, Knowing Bros has kept its role as a stage where guests can promote new projects while connecting with fandoms across generations. Its value is no longer measured only by the number attached to the main broadcast. The show also functions as a place where appearances, short clips and fan conversations continue after the episode has aired.
JTBC's official program page places the broadcast time front and center, introducing the show as airing every Saturday at 9 p.m. Recent VOD listings are also organized around continued circulation: episode 531 is available as a replay, while episode 532 is presented through a trailer, pre-release material and highlight clips. The structure makes it easy for brief scenes from the broadcast to be redistributed after the original airing.
The show's highest point in viewership came with its May 2020 episode featuring cast members from Mr. Trot. According to Nielsen Korea figures for paid households, the episode recorded a nationwide average of 15.5 percent and a metropolitan-area average of 14.0 percent. Its highest minute-by-minute rating reached 21.1 percent, while its target rating among viewers aged 20 to 49 climbed to 5.3 percent.
That peak also shows how much the variety-show environment has changed. Instead of looking only at the live broadcast rating, recent entertainment programs are consumed through clips, guest buzz and the renewed spread of fandom attention. Knowing Bros follows that pattern as performers and their fandoms share short scenes again after the episode, allowing the program to extend beyond its scheduled broadcast window.
The strength of the show's Brother School concept is that it places every guest on the same level. Actors, idols, sports stars and even history lecturers enter the classroom as transfer students. Once they are inside that setup, informal talk and games become the natural rules of the program.
That structure changes the feel of promotional appearances. When a guest introduces a drama, film, album or other project through devices such as a lesson, a talent-show segment or an admission application, the moment reads less like a promotional line and more like a variety-show scene. Even when guests are brought together in unfamiliar combinations, the classroom setting gives the conversation a clear starting point.
Recent bookings have continued to work within the same frame. Episode 530 invited Ha Seok-ju, Kim Tae-young and Kim Young-kwang ahead of the 2026 FIFA World Cup in North and Central America, turning football memories into variety-show material. Another episode used the classroom concept for a lecture-style history subject through a special focused on Danjong.
A girl group special previewed for June brings together members of Brown Eyed Girls, fromis_9, RESCENE and Baby DONT Cry. The planned lineup places artists with experience spanning from the 1.5 generation to the fifth generation in the same classroom, making generational contrast part of the program's format rather than a separate topic.
The chemistry built over time by Kang Ho-dong, Lee Soo Geun, Seo Jang Hoon, Kim Young Chul, Lee Sang-min and Min Kyung Hoon has also recently been joined by Kim Shin Young's addition to the cast. For the long-repeated Brother School format to keep promotional talk from flowing in an overly predictable order, it needs lineups like the June girl group special, where guests from different generations are placed inside the same talk and game structure.
