Understanding OTT vs CTV helps advertisers choose the right formats, measurement approach, and buying strategy—especially when campaigns are planned programmatically.
OTT vs CTV: The Difference
What is OTT?
OTT (Over-the-Top) refers to streaming video content delivered over the internet, without a cable or satellite provider. OTT can be watched on:
- TVs (through streaming apps)
- mobile devices
- tablets
- desktops
Examples of OTT platforms include Hulu, Peacock, Disney+, Max, Prime Video (with ads), Paramount+, and FAST channels.
What is CTV?

Examples of Connected TV devices include:
- Smart TVs
- Roku
- Amazon Fire TV
- Apple TV
- Chromecast / Google TV
- Gaming consoles (PlayStation, Xbox)
Simple rule: OTT is the content environment. CTV is the screen/device.
Connected TV Platforms
CTV advertising runs when an ad is delivered on a connected television screen through streaming apps or device-level inventory. Common CTV environments include:
- streaming services with ad-supported tiers
- FAST channels

What is OLV?

- social feeds
OTT vs OLV
- OTT advertising generally appears in premium streaming environments and TV-like experiences.
