As evidenced by user interface (UI) refreshes by a number of TV operating systems (TVOS) platforms over the past several months, the connected TV (CTV) platform market is entering a new phase.
Leading TV OS platforms are moving beyond basic app navigation toward more personalized, intelligent, and content-driven experiences. Over the past several months, Roku, Amazon Fire TV, Samsung Tizen, Apple tvOS, and Google TV have all introduced significant user interface updates designed to improve content discovery, deepen ecosystem engagement, and position their platforms for an increasingly competitive streaming landscape.
These refreshes come at a critical time for the connected TV market as operating system ecosystems increasingly shape the market rather than hardware alone.
According to Parks Associates research, Tizen (Samsung) is the leading smart TV OS, accounting for 36% of primary smart TVs in the home, giving Samsung significant control over content discovery, advertising, and consumer engagement on connected TVs.
However, Roku’s combined strength across both smart TVs (17%) and streaming media players (43%), makes it one of the most influential OS platforms in the connected entertainment ecosystem, extending its reach beyond any single hardware brand. This shift highlights how platform ownership is becoming a key driver of long-term value through advertising, viewer data, and content distribution.
For content providers, advertisers, and smart home companies, platform partnerships with Samsung, Roku, Amazon and other TV OS platforms are increasingly critical for audience reach and monetization.
The dominance of a few operating systems also creates a fragmented but concentrated market, where developers must support multiple platforms while platform owners gain greater leverage over content placement, advertising inventory, and user experiences. As a result, competition is moving beyond device sales toward ecosystem control and recurring service revenues.
Recent UI refreshes by Roku, Amazon Fire TV, Samsung Tizen, Apple tvOS, and Google TV reflect the growing importance of the TV operating system as the primary point of consumer engagement and while each of these TV OS platforms are moving toward AI-assisted discovery, they clearly have different philosophies for TV UI design and are solving different problems.
Roku
Roku's recent user interface refresh represents the company's most significant home screen update in years, marking a shift from its historically simple, app-centric design toward a more content-driven experience.
The redesigned interface places greater emphasis on personalized recommendations, curated content hubs, and promotional content intended to help users discover shows and movies more quickly. New content rails, recommendation modules, and quick-access features are designed to reduce browsing time and increase engagement across Roku's platform.
The refresh reflects Roku's broader strategy of evolving from a neutral streaming gateway into a more active content discovery platform.
While the updates improve personalization and content visibility, they also increase the prominence of advertising and promoted content throughout the home screen. As a result, the new interface offers more opportunities for discovery and engagement but may feel less streamlined to users who preferred Roku's traditionally minimalist approach.
Amazon Fire TV
Amazon's Fire TV refresh is one of the most substantial functional redesigns among major TV OS platforms, aimed at improving content discovery and simplifying navigation.
The updated interface introduces a streamlined top-navigation layout with dedicated destinations for movies, TV shows, live programming, sports, and other content categories. Amazon has also expanded customization options, allowing users to pin more favorite apps, while improving performance and reducing the number of steps required to find and launch content across streaming services.
The redesign reflects Amazon's strategy of making Fire TV a content-first platform powered by AI and voice interaction. Integration with Alexa and newer AI capabilities enhances search and recommendation features, enabling users to discover content through natural-language queries and personalized suggestions.
While Amazon continues to promote its own services within the interface, the refresh creates a more modern, intuitive experience that better balances content discovery, personalization, and smart-home integration.
Tizen (Samsung)
While not as recent as the previous two UI refreshes, occurring in October 2024, Samsung's Tizen refresh is relevant as it centers on the introduction of One UI Tizen, extending the design language and user experience principles found across Samsung's smartphones, tablets, and other connected devices to the television.
This update emphasizes personalization through user profiles, AI-powered recommendations, and enhanced content discovery features, while creating a more consistent experience across Samsung's ecosystem. Samsung has also highlighted longer software support cycles, positioning its TVs as connected devices that continue to receive feature updates over time.
The refresh reflects Samsung's broader strategy of strengthening ecosystem integration rather than fundamentally reimagining TV navigation. New AI capabilities, including Vision AI features, aim to personalize recommendations and optimize viewing experiences, while tighter connections with Galaxy devices and SmartThings-enabled products make the TV a more central part of the connected home. As a result, the updated Tizen platform delivers a richer and more personalized experience, though it introduces greater complexity compared with the simpler interfaces traditionally associated with smart TVs.
More recently (October 2025), Samsung integrated Perplexity AI into its smart TV platform. Perplexity functions as a conversational answer engine that allows users to ask natural-language questions, conduct research, receive recommendations, and explore topics directly from their TV screens. Unlike traditional voice assistants that rely on simple commands, Perplexity provides contextual responses, follow-up suggestions, and real-time information sourced from the web, enabling use cases that range from discovering movies and planning trips to researching current events and sports. This integration signals Samsung's broader vision of transforming the television from a passive viewing device into an interactive information and discovery platform.
Complementing this capability is Samsung Vision AI, the company's umbrella initiative for bringing AI-powered experiences to its TVs and smart displays. Vision AI combines generative AI assistants, personalized recommendations, content recognition, voice interaction, and AI-enhanced picture and sound optimization within a unified interface.
Together, Vision AI and Perplexity reflect Samsung's strategy of positioning the TV as a central hub for entertainment, information, and smart-home interaction, while differentiating Tizen through advanced AI capabilities and deeper ecosystem integration.
Apple
Apple's latest tvOS refresh takes a notably different approach from its competitors, focusing on visual refinement and user experience rather than major changes to navigation or content discovery.
The centerpiece of the update is Apple's new Liquid Glass design language, which introduces translucent interface elements, enhanced depth effects, and more elegant overlays that allow content to remain visible while users interact with menus and controls. The redesign extends Apple's broader software aesthetic across its ecosystem while maintaining the simplicity and familiarity that have long characterized the Apple TV experience.
The refresh reflects Apple's strategy of prioritizing immersion, premium design, and ecosystem consistency over aggressive recommendation engines or advertising-driven discovery. Additional enhancements include improved profile switching, streamlined app sign-ins, and a more personalized experience for households with multiple users. While competitors are increasingly emphasizing AI-powered content discovery, Apple continues to focus on delivering a polished, intuitive viewing experience that minimizes distractions and keeps attention on the content itself.
Google's recent Google TV refresh is centered on making content discovery more personalized, intelligent, and conversational.
Rather than focusing primarily on visual changes, Google has enhanced the home screen experience with improved recommendations, curated content hubs, and AI-powered search capabilities. The platform increasingly prioritizes content over individual apps, helping users find relevant programming across streaming services more quickly and with less navigation.
A key element of the refresh is the integration of Gemini AI, which enables natural-language interactions for content recommendations, information requests, and broader TV assistance. Users can ask conversational questions, receive tailored suggestions based on interests or viewing habits, and access summaries of news, sports, and other content directly from the TV. This AI-first approach reflects Google's broader strategy of transforming the television into a more interactive and intelligent entertainment hub that is deeply connected to its search, AI, and smart-home ecosystems.
Competitive Outlook
This recent wave of TV OS refreshes underscores a growing shift in the competitive landscape from hardware and app ecosystems toward user experience, content discovery, and AI capabilities.
As streaming services proliferate and content libraries become increasingly fragmented, platform providers are seeking to differentiate themselves by helping consumers find relevant content more efficiently. This places greater strategic importance on recommendation engines, search technologies, and personalization capabilities, potentially increasing the influence of platform operators over viewing decisions and content consumption patterns.
These refreshes also signal an intensifying battle to establish the television as the central hub of the connected home. Amazon, Google, Samsung, and Apple are leveraging their broader ecosystems, including smart-home devices, voice assistants, mobile devices, and AI services, to strengthen customer loyalty and increase platform stickiness.
As a result, consumers may become more deeply embedded within individual ecosystems, raising switching costs and creating competitive advantages for companies with strong cross-device integration.
For content providers and advertisers, the growing emphasis on platform-controlled discovery creates both opportunities and challenges.
Enhanced recommendation systems can improve content visibility and audience targeting, but they also increase the importance of securing favorable placement within platform interfaces. As home screens become more content-centric and recommendation-driven, platform operators may gain greater influence over which services, channels, and programs receive consumer attention, potentially reshaping content distribution and advertising strategies across the streaming ecosystem.
Finally, the emergence of AI-powered TV experiences suggests that future competition will increasingly revolve around intelligence rather than interface design alone.
Platforms that successfully combine personalized recommendations, conversational search, contextual assistance, and ecosystem integration may be better positioned to capture viewer engagement and advertising revenue. This could accelerate industry consolidation around a small number of dominant platforms capable of leveraging AI, data, and ecosystem scale to deliver differentiated user experiences.
