Wispa is a brand of chocolate bar manufactured by British chocolate company Cadbury. Using aerated chocolate, the bar was launched in 1981 as a trial version in North East England, and with its success it was introduced nationally in 1983. It was seen as a competitor to Rowntree's Aero . In 2003, as part of a relaunch of the Cadbury Dairy Milk brand, the Wispa brand was discontinued and the product relaunched as "Dairy Milk Bubbly". As part of the relaunch, the product was reshaped as a standard moulded bar instead of a whole-bar count-line.
