Wispa

Wispa is a brand of chocolate bar manufactured by the British chocolate company Cadbury. First launched in 1981, the bar uses aerated chocolate and was seen as a competitor to Rowntree's Aero (now owned by Nestlé). The Wispa brand was discontinued in 2003 and replaced by a different "Dairy Milk Bubbly", but the original Wispa returned as a limited product in 2007, helped by an internet campaign by enthusiasts, then permanently returned to shops in Britain and Ireland in 2008 due to popularity.
