巧克力的发展在19世纪时经历了两次革命性的发展。1847年，一个英国公司引进了经由软糖巧克力发展而来的固体巧克力，柔滑多样的巧克力完全取代了曾占领世界市场一时的老式巧克力。1876年，在瑞士发生了巧克力的第二次改革。丹尼尔·彼特将牛奶添入巧克力并制造出了产品，也就是今天的牛奶巧克力。

 
Chocolate comes to America in the United States of America, the production of chocolate proceeded at a faster pace than anywhere else in the world. It was in pre-Revolutionary New England-1765, to be exact-that the first chocolate factory was established in this country.

巧克力被引进美国，在那里，它的生产速度是世界最快的。1765年，在新英格兰革命开始时，英国第一家巧克力工厂建立成功。

 
Chocolate has gained so much importance since that time, that any interruption in its supply would be keenly felt.

从那时起，巧克力就大受欢迎，以致于任何供给不足都能被敏锐地捕捉到。

 
During World War II, the U.S. government recognized chocolate's role in the nourishment and group spirit of the Allied Armed Forces, so much so that it allocated valuable shipping space for the importation of cocoa beans. Many soldiers were thankful for the pocket chocolate bars which gave them the strength to carry on until more food rations could be obtained. Today, the U.S. Army D-rations include three 4-ounce chocolate bars. Chocolate has even been taken into space as part of the diet of U.S.astronauts.
世界二战中，美国政府认识到巧克力在营养和海陆空三军联盟团队中的重要性，因此美国政府预留了那时被视为很珍贵的舱位用于可可豆的运输。许多士兵都非常感谢小型巧克力块能在他们拿到配给粮食前让他们维持能量。现今，美国军队食物配给中包括了三块四盎司的巧克力块。巧克力甚至被列位美国宇航员指定饮食的一部分。
