Internet campaigners have prompted chocolate giant Cadbury to bring back its defunct Wispa bar.
The Wispa bar was as popular in the 1980s as the Rubik's cube
The brand vanished from UK shelves four years ago amid declining sales and was replaced with Dairy Milk Bubbles.
But online petitions and campaigns on social networking websites have been calling for Cadbury to think again.
The firm, which has its main factory in Birmingham, has agreed to relaunch the Wispa for a limited period and 23m bars will be available from October.
Cadbury spokesman Tony Bilsborough said: "We have noticed the web interest for some time and the consumer passion has undeniably swayed our opinion to relaunch Wispa.
"This is the first time that the power of the internet played such an intrinsic role in the return of a Cadbury brand," he added.
The return of the Wispa, originally launched in 1981, is scheduled to be for a limited period, but Cadbury has suggested that if sales are high, the chocolate bar could remain on UK shelves.
