When the NWA was founded in 1948 the NWA Board of Directors allowed any NWA member promotions to create their own "NWA World Tag Team Championship" without interference or oversight from the board of directors.  The first of these NWA World Tag Team Championships was created in 1950 in the San Francisco territory, which while billed as a "World" title was essentially restricted to the specific NWA territory.

In 1991 that championship was renamed the World Championship Wrestling Tag Team Championship.
