What is OTT?
Over-the-top (OTT) advertising refers to the delivery method of streaming video content over the Internet, bypassing conventional cable or satellite providers. As the name suggests, over-the-top essentially goes "over” traditional TV channels like cable or satellite.
It is commonly associated with the term "cord-cutters" as it enables viewers to access TV programming using an internet connection instead of relying on traditional broadcast services. Popular examples include Hulu, Netflix, Amazon Prime, Peacock, and Disney+. OTT often utilizes dedicated devices, referred to as OTT devices or boxes, which can be connected to standard displays.
OTT devices come in several forms:
- Some, like Xbox, serve as game consoles as well.
- Others, such as Roku TV, use OTT boxes and specialized remotes.
- And there are those, like Hulu and Netflix, that operate solely through internet-connected smart TVs.
What is CTV?
Connected TV (CTV) refers to any device equipped with internet capabilities that is either connected to or embedded within a TV set and allows users to stream video content. Some examples of CTV devices include smart TVs and popular streaming devices like Amazon Fire Stick and Roku.
OTT vs CTV
How is OTT different from CTV? OTT refers to the delivery method of video content, bypassing traditional distribution channels, while CTV refers to the physical device that supports such video streaming content. For instance, you can watch OTT content — your favorite Hulu show, for example — on a CTV device like a Roku TV.
While OTT and CTV have their differences, they also share several similarities. Both OTT and CTV allow viewers to watch content on-demand, enabling them to choose what they want to watch and when they want to watch it.
The History Behind CTV and OTT
Today, OTT and CTV are anything but interchangeable — but that’s not how it's always been.
OTT began as a catch-all term for any non-traditional TV. Media buyers considered OTT to be any premium video delivered outside of or “over” a set-top box. That meant any and all devices could be considered OTT. For instance, streaming Netflix through your phone or on your smart TV would both fall under OTT.
This all changed in 2021 when the MRC officially changed the definition of OTT to help separate the term from connected TV, which has exploded in popularity over recent years. eMarketer has found that time spent with connected TV devices will make up one-fifth of viewers’ digital time in 2023.
Essentially, the MRC distinguished between "CTV" as the medium (content consumed on a television screen via internet delivery) and "OTT" as a reporting category (encompassing various nontraditional TV video consumption).
The distinction allows for more precise measurement of video consumption on connected devices, such as smart TVs, streaming devices, and gaming consoles. It recognizes the unique viewing experiences and behaviors associated with watching content on these devices.
Who are the major players in CTV and OTT?
Think of the connected TV and OTT landscape as a three-sided market.
- Buyers are advertisers or agencies that seek to promote products, services, or messages through advertising campaigns.
- Sellers: The entities that distribute video-on-demand or FAST channel content, including content owners, app owners and and app store owners.
- Content owners have the rights to certain programming.
- App owners control the streaming apps viewers can download from their connected TV to access popular streaming services or content.
- App stores control the distribution of publisher apps.
- Audience: The consumers or viewers of content on connected TV and OTT platforms. This includes individuals who access streaming services on smart TVs, set-top boxes, streaming devices, laptops or mobile devices
The common thread connecting these three pieces is the medium or device through which streaming content is delivered — specifically smart TVs and other connected TV devices. Think of an Amazon Fire Stick, Roku TV or LG Smart TV. These devices contain the streaming apps through which viewers consume video content.
What makes CTV unique?
From viewability to measurement and more, connected TV has become a distinct term in the world of OTT for a reason. CTV has a number of unique features, including:
Co-viewing: The traditional measurement tools used in mobile or desktop environments may not account for the co-viewing aspect of CTV. Why? CTV advertising often takes place in an environment where co-viewing is common. Multiple viewers may be watching content together on a single television screen, introducing additional complexity in measuring individual viewer attention, engagement, and the impact of ads.
Attribution: Business outcomes like page visits, sign-ups, and purchases driven by CTV ads occur on other devices, such as phones or laptops — making CTV more challenging than in other OTT environments. Because of this, CTV attribution requires piecing together multiple signals from varied sources.
Measurement: The measurement of CTV advertising is largely pixel-based, meaning that viewability and engagement metrics are captured using viewability pixels attached to the VAST tag’s tracking events. Pixel-based CTV measurement can be more challenging than mobile or desktop because traditional measurement tools such as JavaScript and Software Development Kits (SDKs) may not be as readily available or compatible in the CTV space.
Targeting: Targeting on OTT often relies on data collected from individual user accounts or devices. This data can include user preferences, viewing history, and behavioral patterns. On the other hand, CTV targeting typically relies more on contextual cues and aggregated household-level data, as individual user tracking is less prevalent.
Connected TV (CTV) vs. Over-the-Top (OTT)
Key Takeaways
You now know the key differences between over-the-top and connected TV. Need a quick reminder? We’ve compiled our key takeaways below.
- CTV (connected TV) is a subset within the broader concept of OTT (over-the-top). CTV specifically pertains to internet-connected TVs that support video streaming content. On the other hand, OTT refers to the delivery of video content directly over the internet, bypassing traditional distribution channels.
- The CTV and OTT landscape can be thought of as a three-sided market comprising buyers, sellers, and the audience. The main thread connecting these three sides is the streaming app and device, which delivers video content from the seller and buyer to the viewer.
- Traditional measurement tools used in mobile or desktop environments may not account for co-viewing in CTV advertising, where multiple viewers watch content together on a single television screen, leading to complexities in measuring individual viewer attention, engagement, and ad impact.
- CTV attribution poses challenges as business outcomes driven by CTV ads occur on different devices, necessitating the integration of multiple signals in a household device graph to accurately measure and attribute results.
- Targeting on OTT platforms is primarily based on individual user data, including preferences, viewing history, and browsing behavior, while CTV targeting relies more on contextual cues and aggregated household-level data due to limited individual user tracking.
