Disc golf brands come and go. This table documents discs from manufacturers that are no longer in business or have stopped producing discs — sourced from verified defunct brands in the PDGA approval list.
Source: Brand status verified against the UDisc guide to defunct disc golf brands and the PDGA manufacturer approval list. Discs are included only where the parent company has ceased operations or stopped producing disc golf products entirely. Individual disc models from still-active brands are not included here.
