A candy bar is a type of candy that is in the shape of a bar. The most common type of candy bar is the chocolate bar,[citation needed] including both bars made of solid chocolate and combination candy bars, which are candy bars that combine chocolate with other ingredients, such as nuts, caramel, nougat, or wafers.
Many varieties of candy bars exist,[1][2] and many are mass-produced.[3][4] Between World War I and the middle of the 20th century, approximately 40,000 brands of candy bars were introduced.[1][5]
