Which came first
Wikidata, under CC0 1.0. Retrieved 2026-09-13, Hand-curated, then verified by query. Candidates came from two sweeps of the Wikidata query service: every entity with at least 90 Wikimedia sitelinks carrying exactly one best-ranked inception date at full day precision, and a named shortlist of household brands, toys, games and programmes resolved through the English Wikipedia page-props API. Selection is manual and editorial — the mechanic only works when both items are famous to the same person, so the bar is a UK household with a child in it rather than a sitelink count. Every surviving value was then re-fetched by item and rejected unless the property carried exactly one best-ranked statement at day precision, which is what stops a year-precision date shipping as a fabricated 1 January. Items were also dropped where the one stored date is not the date the thing is normally said to have started..
