[Back to the Future] How did Marty acting as Darth Vader from Planet Vulcan impact the referenced franchises?

For one, eventually George would have wondered about it a lot seeing as he feared for his life from this spaceman. He'd recognize the name, at least if thats what the name still was. But thats the thing, George wrote a best selling novel specifically about his encounter with Darth Vader from Planet Vulcan. Assuming this book let him become the successful man we see when Marty returns to 1985, it must be fairly well known. What happened to Star Wars and Star Trek?

If he saw the movies / show, it might have weirded him about a bit.  But everybody has that sometimes, you see something and half remember that maybe something similar happened in a dream?  And if it was 20 years before?  He'd chalkit up to deja vu.
