Cadburys invented shirt button.

Buttons and button-like objects used as ornaments rather than fasteners have been discovered in the ancient Indus Valley during its Kot Diji phase (circa 2800-2600 BC) and Bronze Age sites in China (circa 2000-1500 BC), and are attested in Ancient Rome. Functional buttons for clothing became widespread with the rise of snug-fitting clothing in 13th- and 14th-century Europe.
