Your TV set has become a digital billboard. And it’s only getting worse.

The TV business isn’t just about selling TVs anymore. Companies are increasingly seeing viewers, not TV sets, as their most lucrative asset.

Over the past few years, TV makers have seen rising financial success from TV operating systems that can show viewers ads and analyze their responses. Rather than selling as many TVs as possible, brands like LG, Samsung, Roku, and Vizio are increasingly, if not primarily, seeking recurring revenue from already-sold TVs via ad sales and tracking.

How did we get here? And what implications does an ad- and data-obsessed industry have for the future of TVs and the people watching them?

The value of software

Success in the TV industry used to mean selling as many TV sets as possible. But with smart TVs becoming mainstream and hardware margins falling, OEMs have sought new ways to make money. TV OS providers can access a more frequent revenue source at higher margins, which has led to a viewing experience loaded with ads. They can be served from the moment you pick up your remote, which may feature streaming service ads in the form of physical buttons.

Some TV brands already prioritize data collection and the ability to sell ads, and most are trying to boost their appeal to advertisers. Smart TV OSes have become the cash cow of the TV business, with providers generating revenue by licensing the software and through revenue sharing of in-app purchases and subscriptions.

A huge part of TV OS revenue comes from selling ads, including on the OS’s home screen and screensaver and through free, ad-supported streaming television channels. GroupM, the world’s largest media investment company, reported that smart TV ad revenue grew 20 percent from 2023 to 2024 and will grow another 20 percent to reach $46 billion next year. In September 2023, Patrick Horner, practice leader of consumer electronics at analyst Omdia, reported that “each new connected TV platform user generates around $5 per quarter in data and advertising revenue.”

Automatic content recognition (ACR) tech is at the heart of the smart TV ads business. Most TV brands say users can opt out of ACR, but we’ve already seen Vizio take advantage of the feature without user permission. ACR is also sometimes turned on by default, and the off switch is often buried in a settings menu. Including ACR on a TV at all says a lot about a TV maker’s priorities. Most users have almost nothing to gain from ACR and face privacy concerns by sharing information—sometimes in real time—about what they do with their TVs.

At this point, consumers have come to expect ads and tracking on budget TVs from names like Vizio or Roku. But the biggest companies in TV are working on turning their sets into data-prolific billboards, too.

When TVs watch you back, so do corporations

In recent years, we’ve seen companies like LG and Samsung increase their TVs’ ad capabilities as advertisers become more eager to access tracking data from TVs.

LG, for example, started sharing data gathered from its TVs with Nielsen, giving the data and market measurement firm “the largest ACR data footprint in the industry,” according to an October announcement. The deal gives Nielsen streaming and linear TV data from LG TVs and provides firms buying ads on LG TVs with “‘Always On’ streaming measurement and big data from LG Ad Solutions” via Nielsen’s ONE Ads dashboard.

LG, which recently unveiled a goal of evolving its hardware business into an ad-pushing “media and entertainment platform company,” expects there to be 300 million webOS TVs in homes by 2026. That represents a huge data-collection and recurring-revenue opportunity. In September, LG said it would invest 1 trillion KRW (about $737.7 million) through 2028 into its “webOS business,” or the business behind its smart TV OS. The company said updates will include improving webOS’s UI, AI-based recommendations, and search capabilities.

Similarly, Samsung recently updated its ACR tech to track exposure to ads viewed on its TVs via streaming services instead of just from linear TV. Samsung is also trying to make its ACR data more valuable for ad targeting, including through a deal signed in December with analytics firm Experian.

Representatives for LG and Samsung declined to comment to Ars Technica about how much of their respective company’s business is ad sales. But the deals they’ve made with data-collection firms signal big interest in turning their products into lucrative smart TVs. In this case, “smart” isn’t about Internet connectivity but rather how well the TV understands its viewer.
