Scroll Theater descends from the cinematic tradition of presentation design — Keynote slides, TED talks, and the full-bleed billboards of mid-century advertising. The idea that one message deserves one frame is older than the web.
On the web, Apple's product pages became the canonical example. The 2013 Mac Pro page — a black cylinder floating in darkness, one feature per scroll — established the template. Each viewport was a statement. The scroll was the transition. No navigation was needed because the only direction was forward.
By the late 2010s, JavaScript libraries like ScrollMagic, GSAP ScrollTrigger, and Locomotive Scroll industrialized the pattern. Parallax effects, pinned sections, and scroll-driven animations became standard. But the core of Scroll Theater is not the animation — it is the pacing. Even without JavaScript, a page with full-viewport sections and scroll-snap achieves the essential rhythm: one idea, one screen, one moment.
Today the aesthetic is everywhere high-end brands need to feel cinematic — Tesla, Porsche, Bang & Olufsen, and countless agency portfolios. It has also become the default for startup landing pages that want to signal ambition. The risk is that the form can outweigh the content: when every section demands a full viewport, the ideas had better be worth the real estate.
