Young Gene Roddenberry fell through a temporal anomaly during WWII, and actually met Kirk and Spock. Spock’s attempt to erase Gene’s memories of the encounter was only partially successful, as it subconsciously came out in his later tv writing. TOS in turn inspired one of Amanda Grayson’s ancestors to name their child Spock, a name Amanda recalled when naming her Vulcan son.

No copies of TOS are known to exist in the 23rd century, as Khan attacked Paramount in the 1990’s, feeling a certain episode mocked him.

And now you know the rest of the story. 😉
