The commercial shows a boy studying the solar system using the Redshift planetarium software. He goes through several planets and recites facts about them; then he announces that it's time to "study the Kilrathi system," picks up a flight stick and instantly switches to an Arrow cockpit playing Wing Commander III!
It's amazing to think that 'Kilrathi' was a perfectly explicable word for a national TV spot in 1995. The footage itself is very interesting as well: of course, the instant switch between Redshift and Wing Commander III was impossible at the time... and eagle-eyed Wing Commander fans will also recognize that the game itself is a prettier mockup rather than the released version. The game mirrors the planetarium software with a lush planet image in the background and pairs of high resolution Arrows swoop past the view.
