Therefore the idea of this game can link heavily with the Cold War and radiation paranoias. The series of Fallout games are all about different Vaults which the population were put into some of them rumoured to be in use of social experiments by the government. Because of the constant fear of nuclear war high-tech shelters were built for government officials and families sometimes bought their own in hope of survival till it was safer to come out.
The technology is retro-futuristic, with various Raygun Gothic machines such as laser weaponry and boxy robots. Computers use vacuum tubes instead of transistors, architecture of ruined buildings feature Art Deco and Googie designs, and what few vehicles remain in the world are all 1950s-styled.
Advertising in the 50's mainly targeted housewives with household products and the aim was to tell the audience what they wanted rather than giving them the choice. There are many advertising billboards in certain parts of the Fallout 3 game and show mainly what you expect the public want to hear i.e. Vault Secure!
And here is the advert for the game which I think is brilliant because of the 50's style advert.
