The information portal Wikio was founded in June 2006 by Pierre Chappaz. In December 2009, it was joined by Ebuzzing which is a service bringing together bloggers and companies. The merger enabled Wikio to further establish itself on the European market for social media marketing. Wikio also acquired the Italianbuzz platform Promodigital and in March 2010 it took over Neotia, a Buzz Monitoring and Online Reputation Management Platform.
In September 2010, Wikio and OverBlog fused and created the Wikio Group in order to become the market leader. Pierre Chappaz became the head of this new group. The latest company to join Wikio was Nomao, a local search engine. It merged with the Wikio Group in October 2010.
