The cross-national IR 2.0 study conducted by the University of Leipzig / Department Communication Management in summer 2011 focused on company-owned investor relations websites as well as Twitter, Facebook, YouTube and SlideShare usage for IR purposes by the 150 largest companies listed in DAX, CAC, FTSE, DJIA and Nikkei. The content analysis revealed usage patterns and identified tools, topics, and intensity of use, dialogical approaches and functions. An engagement index offered the possibility for ranking lists within the indices as well as among the different countries. Additionally, the influence of industrial sectors or sales markets was tested.
