The Split Screen Reality: Are TV Ads Actually Personalized?

Remember the days of the universal television commercial? When a nationwide broadcast of the Super Bowl meant that every single household—from a college student in a studio apartment to a retired couple in the suburbs—watched the exact same cheesy car commercial or beer ad at the exact same moment?

Those days are quietly fading into television history.

If you have ever experienced an eerie sense of deja vu while streaming your favorite late-night show, noticing that a commercial break seems tailored a bit too closely to your recent online searches, you aren’t imagining things. Television advertising has undergone a quiet revolution. Yes, TV ads are increasingly personalized, but the way it happens is vastly different from how targeted ads work on your phone or laptop.

The Great Shift: From Mass Broadcast to “Addressable TV”

To understand modern television advertising, we have to look at how we consume content. The rise of Connected TV (CTV)—streaming apps, smart TVs, and digital boxes—has broken apart the traditional, monolithic broadcast model.

In the old days of linear TV (cable and broadcast), television worked on a program-level strategy. An advertiser bought a slot during a popular sitcom because they assumed sitcom watchers fit a certain demographic. Everyone watching that channel got the exact same message.
