Where they've grown or pulled back

DownNothing recorded in 2026; sponsored 1 conference in 2019.

Counted per conference. 2026 is the latest year whose conferences have mostly happened. Tiers use the best tier each year; swatches show the path, oldest first. A conference counts as pulled out only when a later event published a complete sponsor list, since most events don’t say whether their list is complete.

Once or on and off 1

No clear direction, or a gap we can’t confirm because later sponsor lists are incomplete.
