Cadbury is bringing back the Wispa bar in response to demand from internet campaigners. Icons of the eightiesThe confectionery giant will re-launch the Eighties favourite in October for a limited period. It comes four years after the Wispa was dropped because of declining sales. The Birmingham-based chocolate firm said the comeback was a response to online petitions and campaigns on social networking sites such as Facebook and Bebo. Thousands of fans have campaigned across scores of websites to get the Wispa back on shop shelves. Cadbury will produce around 23 million Wispa bars packaged in the original blue wrappers for the relaunch. The comeback could be made permanent if sales figures live up to the online hype. BRING IT ON!!!!
