Sometimes, in marketing theory and practice it is used the generic phrase "manifestations orexhibition events", which actually refers to fairs, exhibitions, economic and/or businessconventions, currently appreciated as being the most effective marketing tools. We are witnessing the enhacement of the interest of companies or organizations to participatein exhibition events (as exhibitors and/or visitors) due to the benefits that can be obtained as aresult of their participation. In a significant extent, the success of an exhibition event depends on the activity of theorganizer. The Chambers of Commerce are institutions which, still since their establishment, setthemselves to be involved in organizing fairs, due to the role played by them in supporting andstimulating the entire economic activity, locally, nationally, and internationally. In this work, we propose to present significant aspects of the history of fairs, presenting a casestudy on the activity of Constanta Chamber of Commerce.
