TV Is Down, Digital Is Up

The channel that defined a generation of campaigns is handing the lead to the screens you scroll — and the shift is reshaping everything from how money moves to what disclosure law can see.

01The Long Reign of Broadcast

For decades, the equation was simple: raise money, buy television. Broadcast and cable together consumed the lion's share of any serious political ad budget, and for good reason. A thirty-second spot on a local news broadcast reached a mass audience with minimal targeting effort. The campaign identified the media market, the station group set a rate, and a media buyer booked the time. The whole machine was legible — a finite number of stations, published political rates mandated by the FCC's lowest-unit-charge rules, and a paper trail that landed in public inspection files anyone could request.

That clarity had real value for transparency, too. Because broadcasters are federally licensed, they have long been required to maintain political file disclosures showing who bought time, when, and at what price. Researchers, journalists, and watchdog groups built entire monitoring practices around pulling those files. The broadcast buy was expensive, but it was visible.

Cable complicated things modestly — rates are not subject to the same lowest-unit-charge rules, and local cable systems fragment the audience across dozens of systems — but the basic shape held. For most of the modern campaign-finance era, television in some form claimed the majority of political ad spending.

02The Crossing of the Lines

Then digital advertising matured, and the math began to shift. Search, social platforms, streaming video, and programmatic display networks offered something broadcast never could: the ability to serve different messages to different voters in the same household, to test creative in near-real time, and to micro-target by geography down to a specific zip code or even a modeled voter file segment. For campaigns trying to stretch a budget, that efficiency was irresistible.

The shift is not a single dramatic event but a slow crossing of trend lines. Broadcast television's share of the total political advertising pie has shrunk cycle over cycle, while digital's share has grown. In a typical recent cycle, digital captures a substantial and rising slice of total spending — illustratively, estimates from ad-tracking firms have placed combined digital platforms in the range of a third or more of total political ad investment and climbing. The precise split varies by race type, geography, and the nature of the spending entity: a candidate committee running in a small media market may still be predominantly TV-driven, while an issue-advocacy group targeting a national audience online may be almost entirely digital.

Streaming — connected TV, or CTV — adds a wrinkle that blurs the old categories. Technically, a viewer watching ad-supported streaming content on a television screen is watching TV. But the transaction happens programmatically, through digital ad infrastructure, not through a broadcast station's sales team. CTV has become a fast-growing line item for political buyers precisely because it combines the visual impact of a thirty-second spot with the targeting capabilities of digital. It is TV by experience, digital by mechanics.

03What the Shift Means for the Money Trail

The channel migration has direct consequences for transparency. Broadcast disclosure is mandatory and structured; digital disclosure is patchy and platform-dependent. The FCC public file regime does not extend to social media platforms or streaming services. Some major platforms have voluntarily built political ad libraries — searchable databases showing who ran what, with what spend range, targeting parameters, and creative — but the standards vary, the data is often aggregated rather than granular, and the libraries can be taken down or modified at platform discretion. No federal statute yet imposes uniform digital ad disclosure requirements equivalent to what broadcast stations must file.

That gap matters especially because dark money flows comfortably through digital channels. A 501(c)(4) social-welfare organization can buy targeted digital ads without identifying its donors, and the platform-level disclosure — where it exists at all — may show only the organization's name, not who funded it. The same dollar that would have generated a broadcast public file entry, complete with rates and schedules, can move through a programmatic exchange with far less visibility.

The practical consequence for anyone trying to follow the money is that digital spending is genuinely harder to track in real time. Broadcast tracking firms can monitor airwaves continuously; digital buys require cooperation from the platforms themselves or post-hoc disclosure by the buyers.

04What to Watch

The long-run direction is not seriously in doubt: digital's share will continue to grow, CTV will keep eating into what was once unambiguously "broadcast" territory, and the transparency architecture built around licensed television stations will cover a shrinking fraction of total spending. The interesting questions now are regulatory — whether disclosure rules will extend to cover digital channels — and structural — whether the concentration of political digital spending inside a small number of large platforms creates new leverage points for both transparency and manipulation. The lines on the chart keep moving. The rules, so far, have not kept up.
