TV
Overview
TV (티비) is an abbreviation for television (텔레비전), referring to an electronic device and broadcasting system that receives video and audio via radio waves, cables, or the internet and outputs them through a screen and speakers. Since its popularization in the mid-20th century, it has become a core home media device, providing diverse content such as news, dramas, sports, and entertainment. Recently, with the integration of digital technology and the internet, it has evolved into a smart TV, transforming from a simple receiver into a central platform for content consumption and interaction.

History and Development
The history of TV began with mechanical television in the 1920s and developed into electronic television in the 1930s. Color TV was commercialized in the 1950s, followed by the transition to digital broadcasting in the 1990s, and flat-panel display technologies such as LCD, LED, and OLED became mainstream from the 2000s onward. Since the 2010s, smart TVs with internet connectivity have become common, accelerating integration with OTT services like Netflix and YouTube.
Technical Composition
A TV is largely composed of a display panel, tuner, processor, speakers, and connection ports. Picture quality is determined by resolution (HD, Full HD, 4K, 8K), refresh rate (60Hz, 120Hz), and panel type (LCD, OLED, QLED, MicroLED). The tuner receives terrestrial, cable, and satellite signals, while smart TVs connect to the internet via Wi-Fi and Ethernet. Latest models support advanced video and audio technologies such as AI upscaling, HDR (High Dynamic Range), and Dolby Atmos.
Types and Classification
TVs are divided by display technology into LCD (backlit), OLED (self-emissive), QLED (quantum dot), and MicroLED (micro LED). By purpose, they are classified into home use, commercial use (digital signage), and portable use (portable TV). Additionally, based on the operating system, they are categorized as Android TV, Tizen (Samsung), webOS (LG), Roku TV, etc., each with different app ecosystems and user interfaces.
Social and Cultural Impact
TV has had a tremendous impact on news and information delivery, popular culture formation, and political opinion shaping. Notable examples include the live broadcast of the Apollo 11 moon landing in 1969, MTV's music broadcasting in the 1980s, and the reality show boom of the 2000s. However, excessive viewing can lead to health issues (vision deterioration, obesity) and social isolation, and problems such as fake news or biased reporting causing information distortion have also been pointed out.
Changes in Viewing Behavior
In the past, people watched according to schedules set by terrestrial broadcasters, but now 'time-shifted viewing'—consuming content at desired times via OTT services and VOD (Video on Demand)—has become common. Additionally, multitasking viewing has increased through linkage with second screens (smartphones, tablets), and real-time reactions and community formation via social media are also active.
Latest Trends
As of 2024-2025, the TV market shows the following trends:
- Deepened AI Integration: Samsung and LG have equipped AI processors to automatically optimize picture and sound quality according to content genre, and are strengthening their role as smart home hubs through voice assistants (Bixby, LG ThinQ).
- Expansion of OLED and MicroLED: OLED has become thinner and lighter, while MicroLED enables ultra-large screens (over 100 inches) through modular assembly, leading the premium market.
- Gaming-Specific TVs: Gaming TVs supporting HDMI 2.1, refresh rates of 120Hz or higher, VRR (Variable Refresh Rate), and ALLM (Auto Low Latency Mode) are gaining popularity, with more products targeting console (PS5, Xbox Series X) and PC gamers.
- Free Ad-Supported TV (FAST): Ad-supported free streaming services (e.g., Samsung TV Plus, LG Channels) are expanding, allowing viewers to watch various channels for free without cable.
- Sustainability: Enhanced energy efficiency ratings and increased use of recycled materials are drawing attention to eco-friendly TV products.
