Ahhh, by STD you mean Star Trek Discovery? Finally got it due to that comparison.
What a bad acronym for the show though. Makes it look like you're talking about sexually transmitted diseases
Yeah, I have no clue what CBS was thinking when they chose that title, they know that the fans shorten all of the series titles, they should have realized that STD would be the acronym for Discovery, especially since they knew they were making changes that would be controversial to the Trek fanbase.
TOS- The Original Series
TNG- The Next Generation
DS9- Deep Space Nine
Following the same rules used for Voyager and Enterprise abbreviations, Discovery should have been shortened to DIS by the fanbase, but Trekkies hated the series so much they purposefully shortened it to STD instead.
