Definition-safe research lab
Compare firms, products, services, and aggregate categories within the same published market definition. These observations do not establish a firm-wide share.
Comparable here
Published participant rows inside one selected market definition and a year reported for every selected series.
Never inferred here
Compare source-labeled shares only inside the selected market definition and a shared reported year. Selected rows are never added into a firm-wide total, and labels do not establish legal identity, ownership, control, conduct, or market power.
Selection console
Changing the market replaces the eligible participant set. Every selected series must share the displayed reporting year.
4 selected / 7 eligible. Aggregate or residual rows remain typed and are never treated as standalone firms.
Shared-year snapshot
Bars use the selected market's own published percentage denominator. No selected-share total is calculated.

Longitudinal evidence
Missing years remain blank. Each line uses exact source rows and keeps the selected market definition fixed.
The upper field preserves the market denominator. The lower field changes the question to movement, not share level, and never fills missing years.

Interpretation boundary
Compare source-labeled shares only inside the selected market definition and a shared reported year. Selected rows are never added into a firm-wide total, and labels do not establish legal identity, ownership, control, conduct, or market power.
Page-view usage is a public web-analytics proxy rather than a count of browser users or a revenue measure.

The JSON and CSV routes preserve the selected market, participant order, and shared year. The history route returns all published years for those labels.
