Chocolate chips are small teardrop shapes of sweetened chocolate. They are found in a number of desserts and sweets, but they are most well known for the classic chocolate chip cookie. It is not exactly clear which chocolate manufacturer invented chocolate chips. Hershey states they have been selling chocolate chips since 1928 and are on record for the Hershey's kiss (a large individual drop of chocolate) becoming commercially available in 1907; however, the popularity of chocolate chips did not take off until 1937 with the creation of the Toll House cookie. Ruth Graves Wakefield of the Toll House Inn of Whitman, Massachusetts, added cut-up chunks of a semi-sweet Nestlé chocolate bar to a cookie recipe. The cookies were a huge success; in 1939, Nestlé offered Wakefield a lifetime supply of chocolate in exchange for her recipe, which they printed on the packaging of a chocolate bar. In 1941, Nestlé began selling chocolate chips commercially.
