I didn't think they should include tapes with magazines, but offer them as a separate service one could pay for.
Nintendo also sent out a VHS tape (at least in the U.S.) to many SNES owners that was a promotional video for Donkey Kong Country explaining the technology of the game and at the end it showed about 5 seconds of Killer Instinct. I'm not aware of any other time they did that or of any company doing a similar thing.
