Most adverts don't tell you very much about the products. Especially car adverts, which usually either sell them as ways for young people to be independent or confident, or for family holidays. They're selling you a lifestyle rather than a product. Even though we all know the reality is very different.
The 1984 Mac advert references George Orwell's Nineteen-Eighty-Four, so you get the idea that the Mac is a rebel against mindless conformity.
This Amiga ad references 2001: A Space Odyssey with the Amiga playing the part of the Monolith that stimulates technological advancement.
Better than the ads that I remember anyway, that seemed to market Amiga like toys.
