Claude-Jean Bertrand pravi, da je sistem odgovornosti medijev (Media Accountability System - mas) vsaka nevladna dejavnost, ki jo uvajamo, da bi se mediji zavedeli potreb in želja javnosti, in ki ponuja poti, da bi mediji lahko ugotovili, koliko te potrebe javnosti tudi zares zadovoljujejo.
Claude-Jean Bertrand maintains that parts of the Media Accountability System (mas) are all non-governmental activities aimed at bringing the media to recognize the needs and wishes of the public. Furthermore, such activities furnish the media with methods for establishing to what extent they actually meet the needs of the public.
