From Hollywood’s Golden Age and the Mad Men era to the digital boom: how the treatment became the world’s go-to format for commercial storytelling

The terminology “treatment” was borrowed from Hollywood, but for a long time it primarily belonged to the film and television realm. In advertising circles, if anything similar existed, it may have been referred to simply as a proposal or an approach write-up, but such instances were relatively rare.

The concept of a treatment originated in the film industry long before it was adopted in advertising.

In Hollywood’s early days, as far back as the 1920s and 30s, studios would ask writers to create a narrative outline or summary of a movie — essentially a prose sketch of the story — before a full screenplay was written.

This document was meant to “detail how they would adapt a book or story into a screenplay, usually by telling a version of the story in narrative form.” By the 1930s, the term “treatment” was already in common use. In 1935, Mary Pickford hired a screenwriter to “write a treatment” of her novel as a potential film adaptation. The word “treatment” itself hints at its purpose: historically, to “treat” could mean to negotiate or propose terms, so a treatment in the creative sense is essentially a written pitch or proposal of how a film will be “treated.”

Throughout the 20th century, film treatments became a standard step in development.

By Hollywood’s Golden Age and beyond, studios and financiers expected to see a treatment first to decide if a project was worth pursuing. In fact, a well-written treatment became crucial to get one’s script read by executives — it “will often be the first document to be glanced over” when you submit a screenplay. As one screenwriting reference notes, “a film treatment states how the audience will experience the film” and should immerse the reader in the tone and world of the story.

Both formats — film treatments and TV show bibles — have been used for decades, establishing a tradition of written vision summaries that the advertising world would later draw upon.

Meanwhile, in commercial production, the process was very different. In the mid-1900s, during the rise of TV advertising, commercials were typically conceived and scripted by advertising agencies. Directors were hired to execute a pre-written script or storyboard provided by the agency, and their selection was often based on reputation or showreels rather than detailed written proposals. In practice, a director might discuss their ideas in meetings or calls, and an agency producer would choose a director largely on the strength of their past work and a verbal pitch. Any detailed visualization — such as storyboards or reference photos — was usually handled by the agency’s creative team ahead of time, not by the director in a standalone document.

The focus was on agency concepts and scripts, and directors were seen more as craftsmen executing the agency’s vision, especially in the classic 1960s through 80s era of advertising. This doesn’t mean directors had no creative input — many did — but the formalized pitch document we now call a director’s treatment was not yet a regular requirement.

According to industry insiders, the shift was rapid. “In ye olden times,” as one commercial producer quipped, a director might be “shocked [at] being asked to write up a couple paragraphs in a Word doc about his idea.” This was roughly 15 to 20 years ago — around the mid-2000s — when some agencies and clients first started requesting written explanations of a director’s idea for how they would film the commercial.

There isn’t a single individual who can be credited with coining the term for advertising use. Rather, it filtered in organically as the practice took hold in the 2000s. Ad veterans from different countries may recall using different informal words at first — some might have said “write up your approach” or “concept paper” — but eventually everyone began calling these documents treatments.

The continuity of the term also reflects how similar the underlying idea is to a film treatment: in both cases it’s a pitch document describing how you’ll tell the story on screen.

One interesting note on etymology: the word “treatment” in this context can be thought of as putting an idea into a “treatise” or formal explanation, almost like “giving it a treatment” — like an artist’s treatment of a subject. As mentioned, the root “to treat” can mean to negotiate or deal with something, which is exactly what a director is doing — they are treating the agency’s idea with their own creative vision and negotiating that vision in written form.

Megan Kelly, a production company founder, recalls that in the mid-2000s a director being asked for even a short write-up was unusual, but “within a few years… the writing began to evolve.” By the early 2010s, directors — or their teams — were not only writing detailed text but also adding images and design elements to create a more persuasive presentation.

AI-generated. Spelling and image quirks may occur.

By the 2010s, the treatment became a make-or-break document.

It was the director’s opportunity to sell their vision and prove they understood the concept better than anyone else. As one experienced commercial director explains, “The treatment is primarily a sales tool, a chance to recap your pitch call and really lay out how you see the spot… to really communicate your vision with the written word.” It allows the agency and client to compare approaches side by side in a tangible form. Just as a film treatment helps studio executives envision the movie, a commercial treatment helps ad agencies and brands envision the final commercial and feel confident in a director’s plan.

Fast forward to today, and a typical commercial treatment can be a lengthy, visually-rich PDF, often described as looking like a glossy magazine spread. In fact, industry folks half-jokingly say many treatments nowadays “have turned into coffee table books.” They are carefully designed documents with high-resolution reference photos, mood boards, custom typography, and sometimes even animated GIFs or embedded video links.

To put the timeline in perspective: around 2005, a treatment might have been a 1–2 page text email. By 2010, it might be a basic PDF with some images. By 2020, it’s a full-fledged visual presentation that could easily run 10 to 30 pages depending on the project’s scope.

The document also became central to production alignment. Directors began sharing their treatments with crew, sending visual sections to the cinematographer, or casting pages to actors. It wasn’t just a pitch tool anymore — it became part of how the job was executed. Agencies also saw the benefit. Treatments gave clients a preview of tone and execution before anything was shot, which reduced surprises later on.

The format will likely continue evolving. AI-generated imagery is already being explored as a new source of reference visuals. Some platforms are beginning to replace traditional PDF and InDesign workflows. And in many cases, directors are creating lookbooks that blur the line between treatment and creative development. But the core remains the same — treatments give form to an idea.

And for now, whether you’re pitching a Super Bowl spot or a two-day shoot for a local brand, the treatment is the one place where your voice, vision, and logic all live in one document. It’s not about gloss. It’s about clarity.

And in a fragmented industry, clarity still matters.
