The term Blaster had been used in sf stories, and novels for years before FP. Block and Adler had a very good understanding of written sf, and they used it well. They also had a good handle on mythology, see the deleted Unicorn principle scene in the new dvd.
I believe that FP was also the first use in a movie of Hyperspace, Hyperdrive, and Asimov's three laws of robotics (unnamed) to name three. Note also that Chief Quinn was using wireless earphones.
