Digital ad revenue grew 7.3% to $225 billion in 2023

The signal

In the advertising sector, the IAB/PwC Internet Advertising Revenue Report, published 16 April 2024, states that US internet advertising revenue reached $225 billion for full-year 2023, a 7.3% increase over 2022. The report describes itself as being in its 28th year, run jointly by the Interactive Advertising Bureau and PwC Advisory Services. That growth rate sits below 2021's double-digit expansion but above 2022's pace, which the same series measured at 10.8% to $209.7 billion. The report's own press release breaks the total into formats: retail media at $43.7 billion, up 16.3%; digital video at $52.1 billion, up 10.6%, with connected-TV and OTT accounting for 42% of that figure; audio at $7 billion, up 18.9%; social media at $64.9 billion, up 8.7%; search at $88.8 billion, up 5.2%; and display at $66.1 billion, up 4%.

The evidence

The press release describes the survey's method: PwC collects data directly from companies that sell advertising on the internet, supplemented with publicly available corporate data, covering desktop, mobile, ad networks, exchanges and email advertising. PwC states plainly that it does not audit the submitted figures; it compiles the aggregate result while keeping individual company data confidential. That is a meaningful qualification for a strategist reading category shares: retail media's 16.3% growth is a rate applied to a self-reported base, not an independently verified total. The report is nonetheless the industry's longest-running series for this metric, which gives its year-over-year comparisons more weight than a single new survey would carry, even without an audit trail.

Timeframe and confidence

This is an editorial reading: a single annual print with a long back series behind it is strong evidence of direction, since advertising spending broadly recovered after 2022's slowdown, but weaker evidence of the precise category splits, because those depend on which companies chose to report and how they classified their own revenue. Retail media in particular is a newer category without a stable definition across the whole run, so its share should be read as directional rather than exact.

What would change the reading

A subsequent edition showing retail media's growth rate converging with the rest of the market, rather than continuing to outpace it, would suggest 2023's figure reflected a category still being built out rather than a durable shift in ad budgets. A widening gap between the reported total and figures independently disclosed in advertising companies' own SEC filings would weaken confidence in the aggregate.

• Which companies contributed data to a given year's total, and has that panel changed in ways that would affect the growth rate?
• Does a category's reported share reflect genuine budget reallocation or a broader definition capturing more transactions than before?
• How does the reported annual growth rate compare with the same companies' own quarterly revenue disclosures?

The headline number is useful as a scale marker for the US digital advertising market, but its category breakdown is a vendor-compiled estimate, not an audited census, and should be treated accordingly when used to justify a specific budget shift.
