TGI or (Target Group Index) is the longest established single source marketing and media survey in Britain and was established by BMRB in 1969. TGI has since expanded into over 60 countries with over 700,000 people being interviewed every year. In Britain, TGI collects information from a representative sample of around 25,000 adults annually, the data is released quarterly. The survey asks questions covering consumer attitudes, motivations, media habits and purchase behaviour. TGI is a single source survey meaning respondents have to fill out the entire questionnaire, covering all question areas. Any TGI variable can be cross-analysed with another TGI variable. TGI is used by media owners, agencies and brand owners. In 2005, Enlightenment was established to provide consultancy for brand owners. In 2008, Kantar Media created a commercial partnership with CultureMap to create a business version of TGI, Business Culture Index, an annual survey of company behaviours and attitudes for the UK's audience of SME businesses. In India, TGI is managed by IMRB International on behalf of Kantar Media. In 2010, Kantar Media began working with Kantar Worldpanel to create a new product, TGI Worldpanel, combining the consumer purchase data from Kantar Worldpanel with information on media consumption, leisure activities and attitudes collected via TGI. The first release of this data was planned for release in early 2011. TGI is an operating company within Kantar Media, which in turn, is part of Kantar Group, WPP Group's information and consultancy division. ==External links== * (TGI website ) * (Global TGI website ) * ( TGI Europa website ) * (Enlightenment website ) * (TGI SA website ) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Target Group Index」の詳細全文を読む スポンサード リンク
