Quick Answer: What Do Those Percentages Actually Mean?

In South Korea, television ratings measure the percentage of total television households tuned into a broadcast, not the percentage of individual human viewers. A “10% rating” means that 10 out of every 100 television households were actively watching that specific program. Furthermore, Korean ratings are split into two distinct tiers: terrestrial (free-to-air) networks like KBS and SBS, where double-digit ratings (10% to 15%+) are the gold standard, and cable (pay-TV) networks like tvN and ENA, where crossing 5% to 7% represents major commercial hit status.

Crucially, domestic television ratings track only live and scheduled linear broadcasts within South Korea. Global streaming views on platforms such as Netflix, Disney+, or TVING are not captured in these official broadcast television figures.

Executive Summary: Demystifying the K-Drama Viewership System

Every morning, Korean entertainment outlets report viewership ratings from the previous evening, announcing figures like 15.9% for a weekend family drama, 7.4% for a cable romance, or 11.7% for a Friday-Saturday crime procedural.

Yet to global fans accustomed to digital streaming metrics, these broadcast numbers raise key questions: Why is a 7% rating on tvN a major triumph while 7% on KBS is modest? Why are terrestrial and cable channels ranked separately? By examining verified September 2026 archival broadcast data, this guide explains how Korean television ratings work and how performance is benchmarked.

From the Archive: Real September 2026 Ratings Benchmarks

To understand how the rating system operates in practice, examine the following verified archival performance data from September 2026:

Data Note: As of September 27, 2026. Figures represent verified nationwide household television viewership percentages compiled from official broadcast tracking logs. Viewership totals reflect household reach.

Household Ratings vs Individual Viewers

The fundamental rule of Korean television measurement is that the primary published figure is household rating (가구 시청률).

Television rating systems track sample households with electronic meters. If a sample home tunes in, the entire household counts as viewing, regardless of whether one or multiple family members are watching.

Ratings are reported in two primary geographic metrics:

Nationwide (전국): Aggregates sample data across the entire country.
Metropolitan Area (수도권): Specifically samples Seoul and surrounding urban areas, where mini-series often register slightly higher numbers.

Terrestrial vs Cable: Graded on Different Curves

The most common misconception among international viewers is comparing a cable drama rating directly to a public terrestrial broadcast. Terrestrial and cable operate under different distribution models in South Korea.

1. Terrestrial Networks (지상파: KBS, SBS)

Terrestrial networks are free-to-air public broadcasters accessible via universal signals without a paid subscription. Because every television set in South Korea receives these channels automatically, their baseline viewership is higher. A rating above 10.0% signifies a solid hit, while flagship weekend family dramas frequently exceed 15.0%.

2. Cable / Pay-TV Networks (케이블 / 유료플랫폼: tvN, ENA)

Cable channels require a paid cable, satellite, or IPTV subscription. Rating tables separate “Paid Platform Standard” (유료가구 기준) from universal terrestrial charts. A rating of 4.0% to 5.0% on cable is considered healthy, and breaking past 7.0% (such as Four Hands, Two Sonatas at 7.486%) marks a major commercial success.

Live Broadcasts vs Reruns: The Meaning of `<본>` (Bon-bang)

In Korean television schedule logs, you will notice character tags attached to program titles:

`<본>` (Bon-bang / 본방송): Designates the primary live broadcast of a new episode.
`<재>` (Jae-bang / 재방송): Designates a scheduled encore re-broadcast.

Korean networks re-air drama episodes throughout the week to expand audience reach:

SBS live broadcast of Flex X Cop Season 2 reached 11.7%.
A daytime weekend rerun of the episode scored 3.8% on SBS.
Secondary cable syndication on ENA scored 1.379%.

These encore broadcasts capture substantial viewership outside the original live window.

Daily vs Weekly Ratings: Why Weekly Numbers Can Look Higher

Viewers often ask why a drama weekly rating can differ from—or appear higher than—an individual daily broadcast rating.

For instance, archival records for the KBS2 weekend drama Love Is Coming show:

Daily rating (September 6, 2026): 14.5%
Weekly rating (Aug 31–Sep 6): 15.4%

Weekly and daily charts are compiled separately, and our archive does not detail the weekly calculation, so we report both numbers exactly as recorded.

Do Global OTT Platforms (Netflix, Disney+) Count in Korean Ratings?

The Short Answer: No. Korean television ratings measure domestic linear television viewing. International viewing on platforms like Netflix or Disney+ is logged internally by streaming services and has zero impact on domestic broadcast ratings. Similarly, domestic streaming on platforms like TVING is tracked via digital metrics rather than broadcast television meters. A drama can achieve global streaming buzz with modest domestic television ratings, or lead domestic ratings without international streaming availability.

Frequently Asked Questions (FAQ)

What is considered a good TV rating for a K-drama?

On public terrestrial networks (KBS, SBS), a rating over 10% is considered a solid success. On cable networks (tvN, ENA), where viewing is subscription-based, crossing 5% is a healthy hit, and surpassing 7% is a major commercial success.

Why are cable drama ratings usually lower than terrestrial ratings?

Terrestrial networks are free-to-air channels accessible on every television set in the country via public airwaves. Cable networks require a paid subscription, creating a different baseline sample pool and viewing habit.

Do Netflix or Disney+ views count in Korean TV ratings?

No. Official Korean television ratings measure domestic, live and scheduled linear television broadcast viewing. Global on-demand streaming numbers are tracked independently by streaming platforms.

What is the difference between daily and weekly ratings?

Daily ratings measure the performance of a specific episode broadcast on a single day. Weekly ratings aggregate performance across the full seven-day cycle, often reflecting multi-broadcast measurements across the programming week.
