What the thing is
Campaign advertising is media-based propaganda designed by political consultants and staff to influence political debate and voting.
Where it came from
It emerged with mass broadcast media: Eisenhower’s 1952 TV spots marked its modern form. Candidate-centred advertising rose in the US around 1910, but TV scaled its reach and technique.
Before television, the work was physical. In 1948 Harry Truman shook about 500,000 hands and covered 31,000 miles. In 1952 Eisenhower made forty twenty-second spots, “Eisenhower Answers America”, filmed in one day with visitors to Radio City Music Hall asking about the Korean War, government corruption and the economy. The 1964 “Daisy Girl” spot, a child counting daisy petals before a nuclear countdown, is described as one of the first negative ads. It ran for under a minute and aired once. In 1984 Reagan’s campaign turned to positive, emotional imagery of Americans going about daily life, which proved more successful than attack ads.
What it gets right
It exposes the engineered nature of political persuasion. Campaign ads are propaganda, not information. They are built by consultants, not journalists. They target voters, not inform citizens.
How much they move anyone is a separate question. Lynn Vavreck is quoted as saying that campaign ads have small effects that decay very rapidly, but enough accumulates to make outspending an opponent seem a necessity. Her study with Alexander Coppock and Seth Hill tested 49 advertisements in 59 experiments on 34,000 people and found small persuasion effects regardless of context, message, sender or receiver. A 2021 study in the American Political Science Review found that television ads do affect election outcomes, especially in down-ballot races.
The form can also be turned on a ruler. Before Chile’s 5 October 1988 referendum on Pinochet’s rule, his opponents were given fifteen minutes of national airtime a day for 27 days. Their campaign had no candidate and, rather than attack ads, used joy, “alegría”. Of 7.2 million votes cast, 3.96 million opposed the regime.
What it gets wrong
It treats regulation as a technical fix. Bans on broadcast ads in the UK or EU do not stop distortion—they shift it to digital, unregulated channels where microtargeting and deepfakes now operate.
Even the broadcast rules are contested. The European Court of Human Rights has held that outright bans on political advocacy advertising may breach Article 10 of the European Convention on Human Rights, yet upheld the UK ban, accepting a “risk of distortion” of debate by wealthy groups. In the US, the Bipartisan Campaign Reform Act of 2002 addressed “soft money” but did not require that campaign advertising be verifiable.
Why it matters now
Digital platforms have fractured regulation. While the EU introduced 2024 rules, Turkey criminalised misinformation in 2022, and South Korea banned deepfakes in 2023, the US and Australia still impose minimal content oversight—despite documented prevalence of misleading ads.
In Australia, polling found that 72% of voters encountered misleading political ads during a campaign and 42% saw them daily. The Australian Consumer Law bars misleading or deceptive conduct but does not apply to claims in political advertising, and South Australia’s truth-in-advertising law is the model advocacy groups want applied nationwide. Penalties elsewhere are heavy: South Korea’s ban on AI-generated deepfakes in election campaigns, which applies in the 90 days before an election, carries up to seven years in prison, and Turkey’s Article 217/A, which covers misleading information, up to three years, with critics warning it could be aimed at opposition messaging and independent journalism.
Is it worth your time
Yes—if you care how political power is sold, not just who wins.
