Family Deep Dives

Each family expands into a hierarchical sub-table with the same periods, visual language, and interactive tools as the core table. Each sub-table is an illustrative, editorially curated expansion of one column of the core table: its anchor works have been checked, but its structure and tiers are less developed than the core table's and should be read as a guide for exploration rather than a definitive account of the stream. Like the core table, each sub-table is drawn through a marketing strategy lens, so it covers its topic as it bears on marketing strategy; work from consumer behavior, psychology, and other fields appears where it shaped strategy research, and is otherwise outside the table's scope rather than missing from it.
