Advertising Agency
An advertising agency is built around paid media — making the work and buying the placement that puts it in front of the right audience. The label has shifted over the last twenty years. The discipline has not. Advertising agencies still exist to spend money on attention and turn it into demand.
What is an advertising agency?
An advertising agency is a company that creates and places paid advertising for brands. Television, print, out-of-home, radio, digital, social, programmatic — the channels have multiplied, but the core function has stayed the same since the 1920s. Take a brand, build a campaign, buy the media, measure the response, do it again.
The simplest mental model: an advertising agency is a creative agency that leads with paid distribution. The creative work is built to run inside a media plan, and the media plan is often as strategic as the creative. Many advertising agencies still operate the classic split between the creative department and the media department, sometimes inside the same building, sometimes as separate companies inside the same network.
What does an advertising agency do?
The work falls into four broad areas.
Strategy. Advertising strategy, audience targeting, media strategy, campaign strategy. Figuring out who to talk to, what to say, where to say it, and how often.
Creative. Concept development, copywriting, art direction, TV commercials, print, out-of-home, digital, paid social.
Media. Planning and buying the placements — which channels, which audiences, which moments, what budget split. Negotiating rates, optimising mid-flight, reporting on what worked.
Production. Making the actual ads — film shoots, photography, post-production, music licensing, OOH printing, digital build, all the operational machinery that turns a script into something a media plan can run.
Advertising agency vs creative agency vs marketing agency
| Advertising agency | Creative agency | Marketing agency | |
|---|---|---|---|
| Leads with | Paid campaigns and media buying | Ideas across mediums | Performance and channel growth |
| Money flows toward | Media spend | Production and craft | Channel optimisation |
| Success measured by | Reach, recall, attribution, ROI on media | Cultural impact, brand effect, awards | Pipeline, conversions, CAC, LTV |
| Best for | Brands with media budget to deploy | Brands building brand and content equity | Brands needing growth from channels |
A modern brand often hires all three, sometimes inside the same agency. The lines have blurred — many full-service creative agencies run advertising work, and many advertising agencies have rebuilt themselves around content and brand to escape the commodity media model.
Types of advertising agency
Full-service advertising agencies handle creative, media, and production under one roof. Classic Madison Avenue model. Network shops like the holding-company giants tend to operate this way.
Creative-only agencies make the work but don’t buy the media. Common in the modern landscape — the brand keeps media in-house or hires a separate media agency.
Media agencies do the opposite — they plan and buy media but don’t make the creative. Often partnered with a creative agency on the same brand.
Performance agencies — sometimes called digital advertising agencies or paid media agencies — focus narrowly on paid search, paid social, programmatic, and direct-response work where the success metric is conversion, not awareness.
Specialist advertising agencies focus on a vertical — pharmaceutical, financial, B2B, automotive, multicultural — where the regulatory or audience knowledge is hard to fake.
Who works at an advertising agency?
The classic structure splits into account, planning, creative, and media.
Account: account director, account manager, account executive. The interface with the client.
Planning / strategy: strategist, brand strategist, communications planner, cultural strategist.
Creative: creative director, art director, copywriter, designer, sometimes paired in the traditional art-director-and-copywriter team.
Production: producer, executive producer, director, editor, post supervisor.
Media: media planner, media buyer, programmatic trader, data analyst.
How are advertising agencies priced?
Three models dominate.
Project fees for a defined campaign — strategy, creative, production, often with media handled separately or on top.
Retainers for ongoing creative output and account servicing.
Commission on media spend — historically 15%, now usually 5–10% — where the agency takes a percentage of the media budget it places. Less common than it used to be, but still present in some markets.
Performance-based pricing exists at the digital and direct-response end of the market — agencies charging on conversions, qualified leads, or revenue share — but it’s rare in brand-building advertising work.
Advertising agency vs RIOT
RIOT is a creative agency, not an advertising agency in the classic sense — we don’t run media buying. The work we do for advertising-led briefs sits inside our marketing, storytelling, and video production services, and we partner with media specialists when paid placement is part of the scope. The work tends to look more like branded content, brand films, and integrated campaigns than traditional 30-second TV spots.

Frequently asked questions
What’s the difference between an advertising agency and a creative agency?
An advertising agency leads with paid campaigns and the media that distributes them. A creative agency leads with ideas across mediums — brand, content, film, identity, digital, experience. The work overlaps; the centre of gravity is different.
Do advertising agencies still buy media?
Some do, many don’t. The unbundling of creative and media has been one of the biggest structural shifts in the industry over the last twenty years. Many modern advertising agencies focus on creative only, while specialist media agencies handle the buying.
Are advertising agencies dying?
The label is contested. The classic model — full-service Madison Avenue, commission on media, big TV spot at the centre — is shrinking. The function is not. Brands still need work that is engineered for paid distribution, and someone still has to make it. The companies doing that work increasingly call themselves creative agencies, content studios, or production companies, but the discipline persists under different names.
What is a digital advertising agency?
A specialist advertising agency that focuses on digital channels — paid search, paid social, programmatic display, video, native, sometimes connected TV. Usually performance-led, measured on conversion rather than reach.
How do advertising agencies make money?
Three ways. Fees from clients (project or retainer). Commission on media spend (a percentage of what they place). Production margin (a markup on the cost of making the ads). The mix varies wildly by agency and by market.
