TBS used the name `` The Superstation '' since its national launch in 1976 until 1984 .
In 1991 , the word `` Superstation '' was removed from the cable channel 's on-air branding and promotions , rebranding it as simply `` TBS '' ; this continued until December 17 , 1996 , when TBS celebrated its 20th anniversary as a national service , with the channel reverting its name back to `` TBS Superstation '' ( promotions for the channel 's programming beginning at this time until 2004 often verbally referred to the national feed only as `` the Superstation , '' a moniker that had previously been used from its national launch as a superstation in 1976 until 1984 ) .
