Facebook a social networking site set up a campaign to re-launch Wispa chocolate bars. The campaign was so successful that Cadbury gave in and the Wispa bar was back in the shops in August 2007.

Following on from this success several groups on Facebook are now trying to get Wispa Gold re-launched.

Cadbury’s had pulled the bar in 2003 after two decades of declining sales. Tony Bilsborough, a Cadbury spokesperson in an interview said “We have noticed the web interest for some time and the consumer passion has undeniably swayed our opinion to re-launch Wispa. This is the first time that the power of the internet played such an intrinsic role in the return of a Cadbury brand.”

More and more companies are turning to social network sites like Facebook and Myspace as a free marketing tool.
