I'm not so sure. The US doesn't really have much of a tradition of chocolate bars or confectionery in general compared to Europe. There is also the question of what actually counts as chocolate. Much of what is sold in the US could not legally be described as chocolate in Europe. In the UK milk chocolate must have almost as much cocoa as dark chocolate must in the US.
In the US:
Milk chocolate must contain at least 10% cocoa solids, while dark chocolate must contain at least 35% cocoa solids.
