What Is Connected TV (CTV) Advertising?
Connected TV (CTV) refers to any television that can access the internet, whether through a built-in smart TV operating system or an external device such as a streaming stick or set-top box.
CTV advertising is the delivery of video advertisements to viewers watching content on these devices through streaming apps and services. Examples include pre-roll ads on YouTube when watched via a smart TV, in-stream ads on streaming platforms, and mid-roll placements in long-form video content.
CTV sits at the intersection of two powerful media channels. It inherits the brand-building qualities of broadcast television: the large screen, the high-quality viewing environment, the relaxed and attentive audience. At the same time, it brings the targeting, measurement, and flexibility of digital advertising.
Unlike a broadcast television spot that reaches everyone watching a channel at a given time, a CTV ad can be targeted by geography, demographics, interests, viewing behaviour, or household purchasing signals.
The distinction between CTV and OTT (over-the-top) is often blurred in industry conversation. OTT refers to content delivered over the internet rather than cable or satellite, while CTV refers specifically to the TV-screen device receiving that content.
All CTV is OTT, but OTT content is also consumed on phones, tablets, and computers. For advertisers, CTV specifically means the living room or bedroom screen experience, which commands attention differently from a mobile device.
Measurement in CTV advertising has improved considerably. Advertisers can track view-through rates, completion rates, and in some ecosystems, even post-exposure website visits and purchase activity linked to households that were served a specific ad. This closes the loop between brand awareness investments and lower-funnel outcomes in a way that was impossible with traditional television advertising.
Connected TV (CTV) Advertising In Practice
The scenario below is an illustrative example, not a Juicy Designs client result. The figures indicate the scale of effect that connected TV advertising work typically produces, so treat them as indicative rather than measured.
In the South African context, streaming adoption has grown rapidly. Platforms with significant local viewership including Showmax, Netflix, and YouTube on smart TVs all provide access to addressable video advertising inventory, either directly or via programmatic platforms.
Imagine a South African financial services brand launching a new product. It could purchase CTV placements targeting households in Gauteng earning above a certain income threshold, reaching those viewers during their evening streaming sessions with a 30-second non-skippable brand video.
For brands with video content already produced for social media or YouTube, CTV offers a natural extension of reach at a time when audiences are more attentive. The key creative consideration is that CTV viewers are watching on a larger screen in a relaxed environment.
Text needs to be legible at a distance, audio quality matters more than on mobile, and the ad must make its core point clearly within the first five seconds even if the full slot is 30 seconds. Programmatic advertising platforms enable CTV buying alongside other digital channels within a unified campaign, making reach planning and frequency management much simpler for brands managing integrated campaigns across digital touchpoints.
What connected TV advertising is
Connected TV (CTV) advertising is advertising delivered through internet-connected television, that is, ads shown on smart TVs and streaming devices when people watch streaming content (such as ad-supported streaming services, apps and platforms) on their televisions. As viewing has shifted from traditional broadcast and cable television towards streaming, CTV advertising has grown as a way to reach audiences watching internet-delivered video content on the big screen, combining the large-screen, lean-back experience of television with the targeting and measurement capabilities of digital advertising. CTV ads are the video ads shown within streaming content on connected TVs, and they can often be targeted (using data about audiences and viewing) and measured more than traditional TV advertising, since they are delivered digitally, offering advertisers more precise targeting and better measurement than broadcast TV while reaching viewers on the television screen. CTV advertising is part of the broader shift of video advertising towards streaming and digital delivery, and it appeals to advertisers wanting the impact of TV-style video on a large screen with digital targeting and measurement. Understanding connected TV advertising matters because streaming viewing has grown substantially and CTV advertising is an increasingly significant channel for reaching audiences with video advertising on the television screen, combining TV's reach and impact with digital capabilities, so knowing what CTV advertising is, video advertising on internet-connected TVs during streaming, helps a business understand this growing video-advertising channel and consider whether it fits its goals for reaching audiences with television-style video advertising in the streaming era.
Connected TV advertising for businesses
Connected TV advertising offers businesses a way to reach audiences with television-style video advertising on the big screen, combined with digital targeting and measurement, and its suitability depends on goals, budget and audience. The appeal of CTV is that it delivers impactful, large-screen video advertising (with the attention and lean-back engagement of TV viewing) while offering more targeting and measurement than traditional broadcast TV, since it is delivered digitally, so advertisers can reach relevant audiences on the television screen and measure the results better than with conventional TV advertising. It suits goals like brand awareness and reaching audiences with engaging video, and it can be part of a video advertising strategy alongside other channels (like online video and social video). CTV advertising is increasingly accessible through various platforms and, in some cases, through advertising platforms that offer CTV inventory, making it available to a wider range of advertisers than traditional TV advertising once was, though it still typically requires video creative and a budget suited to video advertising. On availability, CTV advertising is available in markets with significant connected-TV and streaming usage, and as streaming has grown in South Africa, CTV advertising options have become available to South African brands, so South African businesses can run CTV campaigns where suitable inventory and platforms are available, reaching local streaming audiences on the television screen, subject to the available platforms and their reach. On creative, CTV ads are video ads, so they require video creative suited to the format and the large-screen viewing experience, and, as with video advertising generally, the length should suit the placement and hold viewers; common video-ad lengths (such as shorter formats) are typical, with the effective length depending on the specific placement, platform and the ad's purpose, so there is no single best length, but concise, engaging video that suits the placement and holds attention is the aim, rather than an arbitrary duration. For a South African business, connected TV advertising can be worth considering where it wants impactful, large-screen video advertising with digital targeting and measurement, reaching local streaming audiences, provided it has suitable video creative and a budget matched to video advertising, and where suitable CTV platforms and inventory are available for its audience. Because CTV combines television's reach and impact with digital capabilities and is a growing channel as streaming expands, it is an increasingly relevant option for businesses seeking to reach audiences with video advertising on the television screen, so understanding CTV advertising and considering it where it fits the goals, audience and budget is a sensible part of a modern video-advertising approach, while recognising it requires video creative and appropriate budget and is best pursued where the platforms reach the intended audience.
FAQ
Can South African brands run CTV advertising campaigns?
Yes. Streaming services with South African audiences including Netflix, Showmax, and YouTube on connected TVs all support pre-roll and mid-roll video advertising. Programmatic platforms with South African inventory also enable CTV placements. The channel is growing as smart TV adoption increases in households across Gauteng, Cape Town, and Durban.
What video length works best for CTV ads?
15-second and 30-second non-skippable formats are the most common in CTV environments. Because viewers are relaxed and leaning back rather than browsing on a small screen, they tolerate slightly longer ad formats than on mobile. Strong storytelling in the first three seconds remains critical to preventing attention loss.
