Digital ad spend: what the market tells a small business
Digital advertising in the United States reached $294.6 billion in 2025, up 13.9% year over year, according to the annual IAB report produced by PwC. What matters for a small business is not the total but the breakdown: growth is concentrating in the channels that tie spending directly to a measurable result.
- The market is growing in double digits even though no major cyclical event supported 2025.
- Social media grew 32.6%, the fastest growth of any format.
- Concentration is intensifying: the ten largest companies capture the majority of revenue.
- A growing market means cost inflation. A flat budget buys less than it did a year earlier.

Programmatic advertising
Programmatic advertising is the automated buying and selling of online ad space, where systems decide in real time which ad to show to which person and at what price. It stands in contrast to direct buying, negotiated one on one between an advertiser and a publisher. It now accounts for the majority of digital advertising revenue.
The state of the market, measured and audited
The annual report from the Interactive Advertising Bureau, produced by PwC and published since 1996, is the industry reference in the United States. It measures reported and audited revenue, not market estimates.
The 2025 figures are all the more significant because the year included none of the events that usually inflate spending: no Olympic Games, no World Cup, no elections.
| Segment | 2025 revenue | Year-over-year growth |
|---|---|---|
| Total | $294.6B | +13.9% |
| Programmatic | $162.4B | +20.5% |
| Social media | $117.7B | +32.6% |
| Video, all formats | $78B | +25.4% |
| Retail media | $63.4B | +18.0% |
| Creators | $37B | Projected at $44B in 2026 |
| Podcasts | $2.9B | +17.6% |
The IAB's chief executive sums up the dynamic this way: the market has reorganized around performance channels, and investment is concentrating where spending ties directly to a business result. That is exactly the logic that should guide a small business.
Two channels deserve separate treatment in the breakdown: Google Shopping for a catalogue, and Instagram for products that are decided visually.
What to know before renewing a budget
The digital advertising market grew 13.9% in one year, according to the IAB report produced by PwC. The consequence is rarely drawn: in a growing market, costs rise, and a budget renewed unchanged buys fewer customers than the year before. Renewing without adjusting is therefore a disguised budget cut.
- Has our cost per acquired customer risen or fallen over twelve months, by channel?
- If our costs rise 10%, how much volume do we lose at a constant budget?
- What share of our budget is committed to channels where the price is set by auction?
- What part of our acquisition does not depend on a price that rises every year?
- At what cost per customer would we stop buying?
A good answer tracks the cost per customer over time and separates auction-priced channels from the rest. A weak answer talks about cost per click, budget spent, or compares to industry averages.
Deciding how to adjust an advertising budget in a market driven up by auctions is an annual trade-off. A 90-minute consultation settles it on your own costs, with a written summary you can present to your management team.
Where the growth is going, and why
Three movements explain most of the increase.
Social media, driven by video and commerce
With $29 billion in additional revenue in one year, it is the fastest-growing segment. The IAB attributes this rise to the surge of the creator economy, deeper commercial integration and continuous improvements in targeting and measurement.
Video, in all its forms
Connected TV, social video, online video and short form together grew 25.4%, against 19.2% the year before. Video is therefore capturing a growing share of every additional advertising dollar.
Retail media, backed by proprietary data
Advertising sold by retailers on their own platforms grew 18%. Its strength comes from first-party data: the seller knows what the person actually bought.
Creator advertising is a separate case. It reached $37 billion in 2025 and grows faster than the advertising market as a whole, with a projection of $44 billion for 2026. It has moved from experiment to a media channel in its own right.
What these figures change for a small business
A total of $294 billion means nothing to a business that invests $30,000 a year. Three readings, however, are directly useful to it.
| Market observation | Consequence for a small business |
|---|---|
| Growth is concentrating in performance channels | The market confirms what measurement already requires: track cost per acquisition, not impressions |
| Programmatic dominates at $162B | You already buy programmatically without knowing it, through Google and Meta |
| Retail media grows 18% | Selling on a marketplace also means buying visibility on it |
| Video captures a growing share | Not producing video becomes a cost disadvantage, not just a stylistic one |
| Creators become an established channel | A targeted partnership can cost less than an equivalent campaign |
| The ten largest capture the majority | Your real options are few, and they set the prices |
What stays in-house is the break-even threshold per product or service: the cost per customer beyond which a sale is no longer worth it. It depends on margin and lifetime value, two figures only the company holds, and without it no decision to stop is possible. What gets delegated is everything that feeds this threshold: tracking cost per customer by channel, spotting auction drift, arbitrating between platforms and testing new formats. A business that knows its threshold can let a provider optimize without ever losing control of the spend.
The invisible inflation of paid media
It is the least discussed consequence of a market growing 13.9% a year, and the most concrete for a budget.
When demand for ad space grows faster than available inventory, the price rises. Gartner documents this on the advertiser side: media cost inflation reduces what each dollar buys, even as marketing budgets stay flat.
The practical consequence is clear. Renewing the same advertising budget from one year to the next does not give a stable budget: in real reach, it is a shrinking budget. An annual report that compares amounts without comparing volumes hides this decline.
On Google Ads, a second erosion was added on August 17, 2026: a campaign limited by its budget now converges toward its target instead of beating it. There too the spend does not move, and the return falls.
There are two responses to this inflation, and only one works over time. Raising the budget follows the market without ever getting ahead of it. Improving the conversion rate lets you pay the same price for a click and get more out of it. It is the only lever that does not depend on auctions.
In a market growing 14% a year, an advertising budget renewed unchanged is a shrinking budget.

Frequently asked questions about ad spend
How big is digital advertising?
$294.6 billion in revenue in the United States in 2025, up 13.9% year over year, according to the annual IAB report produced by PwC. The figure is all the more notable because 2025 included no Olympic Games, no World Cup and no elections.
Which channel is growing fastest?
Social media, up 32.6% to reach $117.7 billion, or $29 billion in additional revenue in one year. The IAB attributes this growth to the creator economy, commercial integration and advances in targeting and measurement.
Has video become essential?
It captures a growing share of every additional dollar. Across all formats, connected TV, social video and short form, it grew 25.4% in 2025 against 19.2% the year before, to reach $78 billion.
Should you increase your advertising budget every year?
Not necessarily, but you should know that a budget renewed unchanged buys less visibility than a year earlier, in a market growing by nearly 14%. The lever that does not depend on auctions is improving the conversion rate.
Has influencer marketing become serious?
It represents $37 billion in advertising spending in 2025 according to the IAB, with a projection of $44 billion in 2026, and it grows faster than the advertising market as a whole. It has moved from experiment to an established media channel.
Do these US figures apply to Quebec?
The absolute amounts, no. The relative trends, largely yes, because the same platforms dominate on both sides of the border and it is they who set the prices and the available formats.
