There is a difference between topping the box office and owning it. Plenty of films reach #1 in a crowded week with a modest slice of the take. A smaller club does something else: it swallows the week whole. Combine the USA Times Event-Movie Index’s two top tiers — Major events and Phenomenons, every film that captured 38.2% or more of an entire week’s U.S. box office — into a single category, call it a Dominant film, and a twenty-year pattern snaps into focus: domination is no longer the exception. It is becoming the norm.
Domination roughly doubled
In the first decade of the index (2006–2015), an average of 7.7 films a year reached the Dominant tier. In the second (2016–2025), that jumped to 13.4 — nearly double. As a share of all event movies, domination climbed from a 40% average to 55%, and in 2025 it hit 74%: of the 27 films that topped a week last year, twenty took 38.2%+ of it.

The mix has flipped
Early in the era, most weeks were shared — a #1 film out front but a crowded field behind it, so the leader’s share stayed in Event territory. Now the opposite is true: in most recent years, the majority of the films that top a week do so by domination, not by plurality. The gold is shrinking; the navy is taking over.
One clean exception proves the mechanism: 2020 collapses to 24%. With theaters shuttered, the films that reached #1 were small ones limping over a low bar — plenty of Events, almost no domination. Take a real market away and the Dominant tier vanishes; hand the market to a few mega-releases and it swells.
The films doing the dominating
At the extreme sit the Phenomenons — Marvel, Avatar, Star Wars, Jurassic World, Top Gun. But the Dominant tier is broader than the giants; it is the whole top half of the market, and it is where the modern box office increasingly lives.

What it means
The theatrical market is consolidating into fewer, bigger events that don’t share the calendar — they command it. For studios with tentpole IP and for premium-format exhibition, that concentration is the whole business model. For everything in the middle — the mid-budget drama, the counter-programmer, the modest comedy — the squeeze is the story: a shrinking share of weeks where anyone else can breathe.
Method: each film’s peak weekly share is its highest single-week take of total U.S. box office as the #1 film, from Box Office Mojo (The Numbers as fallback). “Dominant” = peak tier of Major event or Phenomenon (38.2%+). Complete for 2006–2025; 2026 in progress.
