South Korea’s Broadcasting Industry Faces Third Straight Year of Revenue Decline, With Groundwave Broadcasting Again Projected to Post Operating Losses

South Korea’s broadcasting sector is facing continued financial strain, with industry revenue declining for a third consecutive year, according to a recent report on the state of the market. The outlook is particularly worrying for groundwave (terrestrial) broadcasters, which are expected to record operating losses again this year, highlighting how legacy media economics are being squeezed by shifting viewing habits and rising cost pressures.

Revenue decline extends into a third year

While the direction of travel has been clear for some time, today’s headline is the persistence of the downturn: broadcasting business revenue has fallen for three consecutive years, the report says. The figures point to a sector that has not yet stabilized despite years of experimentation with formats, streaming-adjacent strategies, and digital expansion.

For terrestrial television networks in particular, the business model has historically depended on a combination of advertising demand and audience reach. However, as consumers increasingly split their time across mobile content, online platforms, and global streaming services, that traditional revenue base has faced structural pressure. The decline over multiple years suggests the industry is dealing not only with cyclical advertising fluctuations but also with longer-term shifts in monetization and audience behavior.

Terrestrial broadcasters expected to fall back into operating loss

The report further indicates that groundwave broadcasters are expected to post operating losses again this year. Operating loss projections matter because they reflect more than top-line revenue: they indicate that costs—such as production, staffing, rights acquisition, and technology upgrades—are not being fully offset by earnings.

In practical terms, the projection implies that terrestrial networks may have to absorb weaker cash flow while still meeting obligations that are central to broadcast operations, including content production and compliance requirements. Even when a network improves efficiency, the challenge remains that advertising and sponsorship budgets tend to contract when audiences fragment across platforms, making it harder to sustain revenue at levels required for profitability.

Why the economics are getting harder

Media economists typically point to a few converging forces behind revenue declines in broadcasting:

First, audience fragmentation. Consumers increasingly choose digital-first sources, reducing the time spent on linear schedules that drive traditional advertising inventory.

Second, ad-market reallocation. Advertisers often prefer platforms that offer measurable targeting and performance analytics. As ad budgets move toward digital channels, broadcasters are left competing in a market where the comparative advantage of traditional TV is less pronounced.

Third, the cost of staying relevant. Maintaining high-quality local programming, upgrading systems, and securing content can be expensive—especially when revenue growth stalls. The result is a squeeze on margins that can persist for years.

Although the report focuses on revenue direction and operating-loss expectations, its implications are broader: without a shift in monetization—whether through better performance measurement, new partnership models, or diversified revenue streams—profitability remains difficult for terrestrial players.

Implications for jobs, programming, and public-interest obligations

When broadcasting businesses face multi-year revenue declines, the impacts often ripple across programming decisions and employment. Networks may scale back riskier projects, compress production budgets, or renegotiate rights costs. That can affect both commercial programming and the broader public-interest role that terrestrial broadcasters have traditionally played, particularly in covering major events and producing locally relevant content.

Moreover, operating losses can limit how quickly networks can invest in next-generation distribution—such as improved interactive services, targeted ad products, or digital subscriber bundles that could complement advertising revenue. Even if content quality remains high, funding constraints can slow innovation.

What to watch next

For viewers and industry stakeholders, the key question now is whether broadcasters can arrest the financial decline through structural changes rather than short-term adjustments. The coming quarters will likely reveal whether the operating-loss projection is driven primarily by one-off costs, temporary advertising softness, or persistent demand weakness.

As digital competition intensifies, terrestrial broadcasters may need to accelerate strategies that connect linear audiences with measurable digital engagement, improve ad-tech capabilities, and develop sustainable revenue beyond traditional advertising. Partnerships—such as collaborations with telecom operators, platform integrations, and more data-enabled ad buying—could also become more important as the year progresses.

Ultimately, the report’s message is that the sector is still in a difficult transition. With revenue falling again and operating losses expected for groundwave broadcasters, South Korea’s media industry may face another year of pressure as it tries to redefine what “broadcast profitability” looks like in an increasingly platform-driven market.
