YouTube
Overview
YouTube is the world's largest video-sharing and streaming platform, owned by Google (Alphabet). It was founded in 2005 by PayPal alumni Chad Hurley, Steve Chen, and Jawed Karim, and was acquired by Google in 2006 for approximately $1.65 billion. Its number of monthly logged-in users is currently known to exceed 2.5 billion, and it has established itself as the de facto standard video infrastructure, accounting for a significant share of global internet traffic.
Beyond being a simple video upload site, it has evolved into a search engine, music streaming service, education platform, live broadcasting medium, and the foundational industry of the creator economy.

History and growth
After the first video, "Me at the zoo," was uploaded in February 2005, YouTube drove the explosive growth of user-generated content (UGC). After Google's acquisition in 2006, it overhauled its own advertising system, and in 2007 it introduced the Partner Program, creating a structure that distributes revenue to creators. In the 2010s, with the spread of smartphones, mobile viewing surged and watch time exploded.
Platform structure and features
- Video upload and streaming: Supports up to 8K resolution and adaptive bitrate (ABR) streaming.
- Shorts: A vertical short-form format fully introduced in 2021, it is a strategic core feature responding to TikTok.
- Live streaming: Provides real-time broadcasting and real-time monetization features such as Super Chat and memberships.
- YouTube Music, YouTube TV, YouTube Kids: These differentiated into music, paid broadcasting, and children's services.
- YouTube Premium: A subscription service including ad removal, background play, offline saving, and music.
Monetization model
YouTube's main revenue sources are advertising, subscriptions (Premium), and commerce. Ad revenue is generally split with creators at a 55:45 ratio, and for long-form videos, mid-roll ads can be inserted if the video is 8 minutes or longer. In addition, various direct monetization methods exist, such as Super Chat, channel memberships, and YouTube Shopping.
Algorithm and recommendation system
YouTube's recommendation algorithm combines watch time, click-through rate (CTR), engagement, and satisfaction signals to construct a personalized home feed and recommended videos. The algorithm has a decisive influence on creators' content strategies, and "watch time rather than views" operates as an important metric. At the same time, criticisms continue to be raised regarding filter bubbles, the spread of provocative content, and exposure to content harmful to children.
Content ecosystem
Almost all genres—games, beauty, mukbang, vlogs, reviews, education, music, news, politics, and more—have been reorganized around YouTube. From individual creators to companies, broadcasters, and government agencies, channels are operated, and the MCN (Multi-Channel Network) and creator economy market have formed.
Social impact
YouTube fundamentally changed the way media is consumed. The influence of traditional broadcasting shrank and personal media rose, while social controversies continue, such as the spread of disinformation, hate speech, copyright disputes, and content exploiting child labor. Governments around the world continue discussions over platform regulation and the scope of responsibility.
Latest trends
As of 2024–2025, YouTube's key changes are as follows.
1. Strengthened Shorts monetization: As the Shorts revenue-sharing model took hold, short-form grew into a revenue axis equal to long-form.
2. Expansion of AI-based features: Automatic dubbing (multilingual audio tracks), AI-based content summaries, improved automatic captions, and production tools using generative AI have been introduced.
3. Mandatory labeling of AI-generated content: Labeling policies for synthetic and manipulated content are being strengthened, and deepfake-related regulations are expanding.
4. Response to ad blockers: Restrictions on users of ad-blocking programs are being strengthened, making platform revenue protection policies clearer.
5. Premium price increases and subscription growth: Prices have risen in several countries, and the share of subscription-based revenue is growing.
6. Increase in TV screen viewing: Watch time via smart TVs continues to surpass mobile, reorganizing YouTube as living room-centered media.
7. Intensified short-form competition: Amid competition with TikTok, Instagram Reels, Naver Clip, and others, editing tools and creator incentives are expanding.
8. Regulatory and environmental changes: Policy changes are underway in response to the EU's Digital Services Act (DSA), children's online safety regulations, and more.
These changes show that YouTube is being reorganized beyond a simple video platform into a comprehensive digital ecosystem combining media, advertising, commerce, and AI services.
