Communication and Information Sciences (CIS) is a broad and emerging interddisciplinary field, which is growing steadily. In this field, empirical work based on data is fundamental and topical  It was AEA's challenge, togeter with  EJCM, to organize this first international conference. This conference will be concerned with  reference works on media as well as with most recent work (including preliminary results of ongoing research). The paper discussed should include economic and/or management approaches and a statistical discussion of quantitative data. Any research work involving somme  quantitative analyses (econometrics in a broad sense) is eligible for the conference. The field covered includes both traditional media such as Press, Radio and TV, and the "new” media, such as Internet.
