Our article “Political Information Opportunities in Europe: A Longitudinal and Comparative Study of Thirteen Television Systems” was published in The International Journal of Press/Politics (July 2012 vol. 17 no. 3, 247-274). This study examines cross-nationally and cross-temporally the supply of political information in thirteen European broadcast systems. It also contributes to political communication research by establishing “political information environments” as a theoretically and empirically grounded concept that informs and supplements the comparison of “media systems”.
