Cadbury has once again bowed to the power of social networking site Facebook with the relaunch of Wispa Gold in the UK.

The UK confectionery giant invited three Facebook users – including two who had created a “bring back Cadbury’s Wispa Gold” group on the site – to its Bournville plant to launch production of the product.

The move follows last year’s return of Wispa following a campaign from consumers on Facebook. According to Cadbury, it sold 41m Wispa bars in 18 weeks in 2008.

Cadbury manufacturing manager Warren Smith said: “The campaign from Wispa fans to bring back the bar has been incredible. Listening to the public’s opinion has confirmed that the decision to bring back the bar is the right thing to do.”
