The OTT Advertising Definition
OTT advertising exists because TV no longer depends on a cable box. OTT (Over-the-Top) refers to video content delivered over the internet, so viewing isn’t limited by broadcast schedules or traditional TV distributors. And because streaming is now a primary way people watch, OTT has become a core part of modern media planning. In Nielsen’s June 2025 report, streaming represented 46.0% of total television usage.
OTT vs. CTV (commonly confused)
They’re related, but not interchangeable:
- OTT = the streaming content/apps (Hulu, Netflix, Disney+, Max, Peacock, Prime Video, Paramount+, FAST channels, etc.)
- CTV = the device where streaming is viewed on a television screen (Smart TVs, Roku, Fire TV, Apple TV, game consoles)
A simple way to think about it: OTT is the environment. CTV is the screen.
Where OTT ads appear (and why creative matters)
OTT viewers stream across screens, which means ads must be built to look sharp everywhere — from a living room TV to a laptop to a smartphone.
Many OTT ad experiences also run in a more focused viewing context than scroll-based video:
- full-screen
- long-form content
- lean-back viewing
- stronger completion behavior than skippable environments
Common OTT ad placements include pre-roll and mid-roll breaks inside premium programming, plus certain platform-level placements (like home screen or pause placements) depending on the inventory source.
OTT on CTV devices
OTT content (and OTT ads) can be delivered through:
- Streaming boxes: Apple TV, Fire TV, Android TV devices, etc.
- HDMI sticks: Chromecast, Fire TV Stick, Roku stick devices
- Game consoles: PlayStation, Xbox
- Smart TVs: native apps (Netflix, Hulu, Peacock, Disney+, etc.)
Who’s watching & where the market is heading
The big story is fragmentation: audiences are spread across more apps than ever, and ad-supported tiers keep expanding premium inventory.
A clear example: Netflix reported its ad-supported plan now reaches 94M+ global monthly active users.
(That same milestone was also covered by Reuters.)
On the investment side, CTV continues to be treated as a must-buy channel. The IAB indicates U.S. CTV ad spend is projected to reach $26.6B in 2025, per StreamTV Insider
OTT vs. OLV (Online Video) — the clean distinction
These two are often mixed up, but they function differently in media plans:
- OTT / CTV: premium streaming content delivered via TV-style environments (subscription w/ ads, FAST, device-level inventory).
- OLV: online video that runs across websites and social platforms, often in mixed contexts (in-stream/out-stream, desktop/mobile, feeds).
Both matter — but they are not the same buying environment, and they don’t behave the same from an attention or completion standpoint.
Overview of OTT Platforms
Over-the-top (OTT) platforms deliver video content directly over the internet, bypassing traditional cable or broadcast TV providers. OTT enables content owners and distributors to reach audiences without relying on linear TV infrastructure, fundamentally changing how video is consumed and monetized.
Most OTT services are accessible through internet-connected devices—including smart TVs, streaming sticks, gaming consoles, and mobile devices—without the need for traditional cable hardware. This accessibility, combined with advanced targeting and measurement, has made OTT a core channel for both viewers and advertisers.
Below are some of the most prominent OTT platforms today.
Hulu
Hulu remains a major ad-supported OTT platform, particularly strong in next-day TV viewing.
- Offers current-season episodes, often available the day after broadcast
- Provides ad-supported and ad-free tiers
- Bundled with Disney+ and ESPN+, increasing household reach
- A key destination for advertisers seeking premium TV content with digital-style targeting
Netflix
Netflix has evolved significantly in recent years.
- Now offers a lower-priced ad-supported tier, making it an active player in OTT advertising
- Focuses heavily on original programming, alongside licensed content
- Available globally with one of the largest subscriber bases in streaming
- Ads are limited, premium, and sold at scale, positioning Netflix as a high-impact CTV environment
Disney+
Disney+ is a cornerstone OTT platform for family and franchise-driven content.
- Hosts content from Disney, Pixar, Marvel, Star Wars, National Geographic, and Star
- Offers both ad-supported and ad-free plans
- Frequently bundled with Hulu and ESPN+

Amazon Prime Video
Amazon Prime Video has become one of the most important OTT advertising platforms.

YouTube TV
YouTube TV is a live TV streaming service, distinct from standard YouTube.
- Provides access to 100+ live TV channels, including major broadcast and cable networks
- Functions as a cable TV replacement, delivered via streaming
- Supports live sports, news, and on-demand content
- Advertising opportunities benefit from Google’s advanced data and measurement ecosystem
(Note: Gaming-focused live streaming is primarily associated with Twitch and standard YouTube—not YouTube TV.)
Why OTT advertising works for brands
OTT combines the storytelling power of TV with the control and measurement of digital. That’s why it’s now used for both brand and performance goals, including:
- reach and incremental reach
- frequency management across fragmented apps
- completion signals
- attribution and lift (where measurement is enabled)
And because buying is increasingly programmatic, OTT enables advertisers to reach the right households wherever they stream, not only within one app.
