Audience measurement

Just few months ago, I had a very vague idea of what an audience measurement. After taking the responsibility of marketing for a group of radio stations, I first tried to understand how decisions were made for buyers and sellers of advertising space. I found that I was disappointed. These are the impressions that I wanted to share these notes. Thank you to the professional audience measurement who were willing to answer my questions, who shared with me on their blogs and on my own and who were willing to read and comment on drafts with my cold blood, despite everything I 'had not understood or misinterpreted, despite my ideas sometimes candid and inconoclastes.
