ELI5:Why does Great Britain compete as one nation for the Olympics but not for the World Cup?

Why does Great Britain compete as one nation for the Olympics but, for the world cup you have, England, Whales, Scotland and so on?

In football each of the nation's has their own FA hence they have their own international team. There isn't a similar system for Olympic sorts etc. 

The first ever international match at football was actually Scotland vs England (0-0 draw).
