How the Console Race table is built.

1. Primary metric: lifetime hardware unit sales

Console Race focuses on cumulative worldwide hardware unit sales. It does not track revenue, profit, monthly active users, or subscriptions.

4. Generation labels are editorial, not official

Generation labels are used to make the table easier to read. They are editorial groupings, not official categories from the platform holders.

5. Source hierarchy

Official investor-relations and business-data pages come first. If a company stops publishing a comparable total, the site uses a named secondary source or a labeled estimate.

For readability, the table normalizes displayed totals to one decimal place. When a source only says "more than" a rounded milestone, such as Sony's legacy PlayStation entries, the site may display a floor marker like 117.0 M rather than claim that the publisher disclosed a more precise decimal figure.

6. How estimate rows are handled

Xbox rows are the main example. Microsoft does not publish a comparable lifetime-sales page, so some Xbox figures are labeled as secondary or estimate. If a better direct source appears, the row should be updated.

7. Update policy

Source pages do not update on the same schedule. Nintendo updates regularly. Sony mixes a current PS5 line with older legacy milestones. Estimate rows may stay unchanged even longer.

When a figure changes:

• confirm the new number on the official publisher page if available,
• check that the table label still matches the true source type,
• update related editorial notes if the interpretation changes,
• avoid changing dates or wording unless the underlying content changed.

8. Why this methodology matters for trust

The table should be easy to check. This page exists so readers can see what the site counts and how uncertain rows are handled.
