In approximately the late 1900s, the chocolate bar evolved. Before the introduction of the bar, chocolate had become popular many years but to provide a more convenient way of consuming the chocolate was the idea of creating a chocolate bar. By hand or while on the go, the bars could be packaged and sold to eat easily. By bulk with loose, irregular or formed pieces, up to the invention of the chocolate bar, chocolate had been sold.

The cost of a chocolate bar was five cents, during the Great Depression. After World War II, the price rose to ten cents and remained that price for many years. To the increase in cost to the consumer of many types of chocolate bars, more advanced packaging and advertising contributed. Also adding many more varieties, many chocolate companies still make the same bars they started out with. Clark Bar 1917, Baby Ruth 1920, The Charleston Chew 1922, Three Musketeers 1932, Fifth Avenue 1936 and many more are some popular chocolate bars that are still popular today. Being enjoyed for many years, the Hershey Chocolate Company makes several chocolate bars. In 1938, the Krackel Chocolate bar was introduced and the bars first contained almonds and alongside of the almonds, then in 1939 peanuts were added. Removing all nuts and peanuts, which is the way we know the Krackel bar today, in 1941 the Hershey company changed the direction of the Krackel bar. It is still considered a chocolate bar even when the shape of the York Peppermint Pattie may be round. Still enjoyed today, the Peppermint Pattie was introduced in 1940. Today, many people prefer buying bulk chocolate bars to save on the cost of the chocolates.

As where a sports team, corporation or school uses the chocolate bars to raise money for needed supplies, chocolate bars can be used for fundraising. For use at promotional shows, incentive programs, and customer appreciation or to encourage attendance at board meetings, there are companies that put their corporate logo on the chocolate. To use personalized chocolate bars to mark the day, wedding favors and other special parties, such as Bar Mitzvahs or milestone birthdays or anniversaries, are perfect occasions. Milk chocolate bars are also available these days that are relished by kids.
