Smart TV: What It Is and How to Choose an Internet-Connected Television

A smart TV connects to the internet to stream apps, movies, and music without external devices. Learn how smart TVs work and what to look for when buying.

What is a Smart TV?

A smart TV is a television with built-in internet connectivity and an operating system that lets you run streaming apps, browse the web, and access online content directly, without needing a separate streaming device. Connect it to your home network via Wi-Fi or Ethernet, and you can watch Netflix, Amazon Prime Video, YouTube, Disney+, and hundreds of other services using just the TV’s remote control. Modern smart TVs also function as smart home hubs and entertainment centers, supporting built-in voice assistants for hands-free control, wireless screen mirroring from phones and laptops for presentations and photo sharing, and deep integration with connected smart devices throughout your home.

Smart TV functionality has become standard on virtually all televisions sold today, from budget models to premium 4K TVs. The experience you get depends largely on which operating system the TV runs, as this determines app availability, interface design and responsiveness, software update frequency and longevity, and how seamlessly the TV integrates with your other connected devices and streaming subscriptions.

Smart TV Operating Systems

The software platform is arguably the most important differentiator between smart TVs, directly affecting your daily experience:

OSMajor BrandsStrengths
Google TVSony, TCL, and othersVast app library, Google Assistant, content recommendations
webOSLGIntuitive interface, Magic Remote pointer, fast navigation
TizenSamsungStable performance, SmartThings integration, Samsung ecosystem
Fire TVAmazon, Toshiba, FunaiDeep Alexa integration, affordable models, broad content
VIDAAHisenseSimple, lightweight, fast boot times

Each platform has access to major streaming services, but niche apps and regional services may vary. Check that the specific services you use are available on your chosen platform before purchasing.

What You Can Do with a Smart TV

Beyond streaming video, smart TVs offer music services (Spotify, Apple Music), screen mirroring (AirPlay, Chromecast built-in), video calling (with an optional or built-in camera), casual gaming, and smart home device control. AI-powered features analyze your viewing habits to recommend content across multiple streaming services in a unified interface. Some platforms provide ambient modes that display artwork, family photos, or useful information when you are not actively watching content.

Smart TV vs. External Streaming Devices

External devices like Fire TV Stick, Chromecast, and Apple TV can replicate smart TV functionality on any display with an HDMI port. The advantage of a smart TV is consolidated control through a single remote. The advantage of external devices is that they receive more frequent software updates and can be replaced inexpensively when their performance degrades or new features emerge. Many users use both: the TV’s built-in apps for daily streaming and an external device as a backup or upgrade path when the TV’s software eventually becomes outdated.

Software Longevity and Update Policies

One important consideration is how long the manufacturer commits to updating the TV’s smart platform. Budget TVs may receive software updates for only two to three years, while premium brands typically support their models for four to five years. After updates cease, new streaming apps may not be installable, and existing apps may eventually stop working as they require newer OS versions. This is one reason why a $30 streaming stick can extend the effective smart lifespan of an older TV by several years, making it a worthwhile accessory investment.

How to Choose

1. Verify Support for Your Preferred Streaming Services

Confirm that the TV’s operating system offers native apps for every service you subscribe to. Major services like Netflix and YouTube are universally available, but regional or niche services may only be supported on certain platforms. Check the TV manufacturer’s app store listing for your region.

2. Prioritize Responsiveness and Remote Usability

A slow, laggy interface will frustrate you every day. Read reviews that specifically mention the TV’s software performance, boot time, and app launch speed. A remote with voice search capability significantly improves the content discovery experience, especially on platforms with large app libraries. If possible, try the interface at a retail store before committing.

3. Ensure Adequate Network Connectivity

4K streaming requires at least 25 Mbps of sustained bandwidth. A TV with Wi-Fi 6 support handles congested home networks more gracefully than older Wi-Fi standards. For the most reliable connection, use the TV’s Ethernet port if your setup allows a wired connection. Consider your router’s location relative to the TV and whether a Wi-Fi mesh system might be needed. Dolby Atmos streaming requires additional bandwidth, so if you plan to use spatial audio through a connected soundbar, ensure your network can handle the higher data rates reliably without buffering or quality drops.

The Bottom Line

A smart TV consolidates your entertainment into a single device with a single remote, eliminating the cable clutter and input switching that comes with external devices. The operating system is the key differentiator, so choose a platform that supports your streaming services, offers a responsive interface, and integrates with your existing smart home ecosystem. Keep in mind that software longevity varies by manufacturer; a budget external streaming device can always extend the useful life of a TV whose built-in apps have stopped receiving updates. Focus on the TV’s display quality and smart platform equally, and you will end up with a television that delivers an excellent experience for years. With smart TV functionality now standard across virtually all price ranges, the choice is not whether to get a smart TV but which platform and feature set best matches your streaming habits, smart home ecosystem, and long-term expectations for software support.
