Are TV Ads Personalized? The Evolution of Commercials

Remember when watching television meant everyone in the neighborhood saw the exact same commercial at the exact same time? If a cereal brand bought a spot during a Saturday morning cartoon, every kid across the country watched that exact same tiger shout about cereal being “gr-r-great!”

Today, the television landscape looks entirely different. If you and your friend stream the same show in different houses—or even different rooms—you might see completely different commercial breaks. So, how personalized are TV ads actually getting, and how does the technology behind your screen figure out what to show you?

From Mass Broadcast to “Addressable” TV

To understand modern television advertising, it helps to look at how the medium split into two distinct worlds: traditional linear TV and streaming.

• Traditional Broadcast TV: This is the classic model. Broadcasters transmit a signal over the airwaves, through a cable box, or via satellite. Everyone tuned into that channel during a commercial break gets the exact same ad. Targeting here is broad and based entirely on context—like placing a toy commercial during a children’s show or a car commercial during a sports game.
• Addressable and Connected TV (CTV): This is where personalization enters the picture. Connected TV refers to internet-connected streaming devices, smart TVs, and gaming consoles. When you stream video, advertising technology allows for dynamic ad insertion. This means that when a commercial break starts, a specific ad can be digitally swapped in real-time to match the profile of the viewer.

How Does TV Personalization Actually Work?

Unlike your smartphone or laptop—which are typically personal devices tied to a single user—a television is usually a shared household device. Because of this, TV ads aren’t usually personalized down to a single individual; instead, they are household-level personalized.

Advertisers and streaming platforms use a few key data points to determine which ads pop up on your screen:

1. Geographic Data: Ads can be targeted down to a specific region, city, or zip code. For instance, two households watching the same national news broadcast might see completely different car dealership or local grocery store commercials depending on their neighborhood.
2. Streaming Habits and Context: Algorithms track what types of genres, apps, or programs a household engages with. If a smart TV is constantly streaming cooking shows or sports highlights, streaming apps log those viewing patterns to serve relevant food or athletic brand commercials.
3. Household Device Graphs: Streaming services and smart TV manufacturers link devices via home Wi-Fi networks and IP addresses. If someone in the house searches for a product on their phone or laptop, that data point can sometimes inform the types of commercials that play when everyone gathers around the living room television.

Why Personalization Matters (And Its Limits)

For advertisers, personalized TV ads reduce “wasted spend”. Instead of paying to show a luxury vehicle ad to an audience that may not be in the market for one, brands can focus their budgets on households that fit specific demographic or behavioral profiles. For viewers, it can mean seeing fewer irrelevant commercials and discovering products or services that genuinely match their interests.
