Who Owns Your Smart TV? Fox, Roku, Walmart, Vizio & the New Privacy Battle in Your Living Room

What changed, and what did not

Why the Fox/Roku deal matters

Fox announced a deal to acquire Roku in a transaction that combines Fox’s sports, news, entertainment content and Tubi service with Roku’s connected TV platform, The Roku Channel, first-party data, and a direct relationship with more than 100 million global streaming households.

The deal is not only about Roku sticks. Roku is a TV operating system, a streaming platform, an advertising layer, a home screen, and a distribution path into households.

The credible privacy concern is not that settings changed overnight. It is that ownership changes can reshape incentives around what gets promoted, how ads are sold, how viewing data is used, and how deeply a TV platform connects content, advertising, and measurement.

Walmart and Vizio show the same trend

Fox/Roku is not happening in isolation. Walmart completed its acquisition of Vizio and its SmartCast Operating System in 2024. Walmart tied the deal to connected TV, Vizio’s operating system, and the growth of Walmart Connect, its advertising business.

That should tell consumers something important: the TV operating system is valuable because it is not just a menu. It is the layer between your household and what you watch.

What ACR tracking has to do with this

ACR stands for Automatic Content Recognition. In plain English, it is technology that can help identify what is appearing on a TV screen. Depending on the platform and settings, ACR can support recommendations, audience measurement, ad targeting, and ad effectiveness reporting.

Roku’s own advertising materials describe ACR data as useful for planning, activation, and measurement. Academic research has described ACR as a Shazam-like system that periodically captures displayed TV content and matches it against a content library.

That does not mean every smart TV behaves the same way. It does mean smart TV privacy is not just about whether you have Netflix, YouTube, Hulu, Disney+, Prime Video, or The Roku Channel installed. It is about the TV platform itself.

This is not just a Roku issue

Roku is the current news hook, but smart TV privacy is bigger than one brand. Samsung, LG, Vizio, Fire TV, Google TV, Apple TV, Roku TV, streaming sticks, gaming consoles, and cable boxes all create different privacy and tracking questions.

Some tracking happens through TV settings. Some happens through streaming apps. Some happens through accounts. Some happens through advertising identifiers. Some happens through network traffic.

That is why users should not ask only, “Which TV brand is safe?” A better question is: “Which settings, apps, accounts, and network controls do I actually manage?”

Should you change anything today?

Yes, but not because one company bought another. Change things because smart TVs have become connected advertising and measurement platforms.

• Review viewing data and ACR settings.
• Turn off or limit personalized ads where possible.
• Reset or limit the advertising ID if your platform allows it.
• Review voice data and microphone settings.
• Remove unused apps.
• Check signed-in accounts and watch history.
• Review router firmware, DNS, and admin password.
• Consider a guest or IoT network for smart TVs and connected devices.
• Use router-level VPN coverage for compatible devices that cannot run VPN apps.

Can you use a smart TV as a dumb TV?

Some privacy-minded users avoid connecting the TV itself to the internet and use an external streaming device instead. That can reduce some smart TV platform tracking, but it is not a perfect fix. If the TV remains online, ACR or viewing-data settings may still matter. If you use an external device, that device has its own privacy settings, account data, and network behavior.

Should smart TVs be on a guest or IoT network?

For many homes, yes. A guest or smart-home network can help separate smart TVs, cameras, speakers, consoles, and streaming devices from work laptops, personal phones, and sensitive devices.

This does not make a TV anonymous, but it can reduce unnecessary exposure between device groups and give you a cleaner home network layout.

Where router-level privacy fits

A VPN router is not a magic “delete all TV tracking” button. It does not automatically disable ACR, erase account history, change app privacy settings, or rewrite platform policies.

But router-level privacy can help with the part of the problem that happens at the network level. That is especially useful for smart TVs, Roku devices, Fire TV, Apple TV, game consoles, and other devices that cannot easily run VPN apps.

A router-level setup can also help separate devices, create a dedicated privacy network, support selected-device routing, and reduce the need to configure every device one by one.

Bottom line

Fox buying Roku and Walmart buying Vizio are reminders that the smart TV business is no longer just about selling screens.

The screen is becoming a platform. The platform is becoming an ad network. And the ad network is becoming part of the connected home.

That is why smart TV privacy should not stop at one TV settings menu. Review your TV settings, streaming apps, accounts, and router setup together. The more connected your home becomes, the more important your router becomes as the control point every device shares.
