OTT Service
Overview
OTT (Over-The-Top) service refers to streaming platforms that deliver media content such as video and audio directly to users over the internet, without borrowing the transmission networks of existing broadcast, cable, or satellite operators. As the name suggests—service layered on top of the network—the key point is that while it uses telecom infrastructure, content distribution and monetization are led by the platform operator. Netflix, YouTube, Disney+, TVING, Wavve, and Coupang Play are representative examples, and since the 2010s, riding the spread of smartphones and broadband internet, it has become a central axis of the media market.
Key details
Definition and background
The term OTT began with the meaning that a third party provides content services on top of a telecom operator's network. Netflix's 2007 shift from DVD mail rental to streaming was a decisive turning point, and afterward, as mobile broadband networks such as LTE and 5G and the spread of smart TVs and tablets became intertwined, viewing behavior shifted from real-time viewing according to a schedule to VOD viewing of desired content at desired times. Netflix's entry into Korea in 2016 and the arrival of Disney+ and Apple TV+ in 2019 were events that fully launched the global competitive landscape.
Major platforms
In the global market, Netflix, YouTube, Amazon Prime Video, Disney+, Apple TV+, HBO Max, Paramount+, and others compete. In Korea, domestic platforms such as TVING, Wavve, Coupang Play, Watcha, and Seezn (시즌) are responding by differentiating original content and pricing plans. YouTube forms a separate massive axis with a free model based on UGC (user-generated content), while Netflix aims for a subscriber lock-in effect through large-scale investment in original series and films.
Business models
OTT revenue models are largely divided into four types. These are SVOD, the monthly subscription type; AVOD, the ad-based free type; TVOD, the per-title payment type; and FAST, the free ad-based linear channel. Recently, a hybrid model combining SVOD and AVOD has emerged as the mainstream. Netflix and Disney+ have adopted lower-priced ad plans, pursuing a strategy to secure both price-sensitive users and advertisers simultaneously.
Technical characteristics
The technological foundation of OTT services is adaptive bitrate streaming (ABR). Protocols such as HLS and MPEG-DASH automatically adjust picture quality according to network conditions, and CDNs (content delivery networks) and edge computing reduce latency and traffic load. For content protection, DRM solutions such as Widevine, FairPlay, and PlayReady are applied, and cloud-based transcoding pipelines and machine learning recommendation algorithms determine the viewing experience and retention time.
Market size and competitive landscape
The global OTT market has grown to hundreds of billions of dollars, and the Korean market is also estimated to reach the trillions of won. The axis of competition has shifted from how much content one holds to how strong an original one secures. Accordingly, original production costs have surged, and price increases, account-sharing crackdowns, and bundled partnerships between telecom operators and platforms are following one after another. Sports broadcasting rights and K-content are key objects of contention among domestic and foreign operators.
Latest trends
The biggest trend in the OTT industry in 2024–2025 is the shift from growth to profitability. Netflix increased both subscribers and revenue through its ad plan and account-sharing crackdown, and Disney+ also achieved a turnaround to profit through expanding ad-supported plans and cost restructuring. Competition to secure live sports broadcasting rights has also intensified, making the NFL, MLB, K League, professional baseball, and others major subjects of exclusive platform broadcasting. In Korea, merger discussions between TVING and Wavve are underway, bringing the securing of economies of scale for domestic platforms to the fore, and Coupang Play grew rapidly through a membership bundle strategy. Technologically, AI-based recommendations, automatic dubbing, subtitle generation, and the spread of short-form clips and FAST channels stand out. On the regulatory side, debates continue over network usage fee sharing, content review, platform fair competition, and mandatory domestic content quotas, and governments around the world are seeking a balance between protecting domestic content and protecting consumers.
