How the test was run
The 2006 list is Interbrand's Best Global Brands 2006 (archived Interbrand ranking, with names from the BusinessWeek scoreboard of August 7, 2006). For each brand we wrote the everyday category a shopper would ask about. On 2026-11-01 an AI assistant, Claude (Anthropic), Opus, no web search, via Claude Code, was asked "What are the leading brands in <category> right now?" for every category, 3 separate times, answering from its own knowledge. A brand counts as not named only if it was missing from its own category every time. Sub-brands are not counted as the parent (Merrill Edge is not Merrill Lynch). One assistant, one day: the test is repeated, and every run is kept.
