Talk:Audience measurement/Archives/2015

Diaries
If I'm not totally mistaken, the the following paragraph does not apply to diaries but to electronic methods of measurement. Real time measurement with diaries does not make sense. Maybe it was accidentally written in the wrong section? Please review: "Data is also collected down to the level of listener opinion of individual songs, cross referenced against their age, race, and economic status in listening sessions sponsored by oldies and mix formatted stations. IBOPE was the first realtime service for audience measurement of the world, it started in São Paulo in 1942." — Preceding unsigned comment added by 158.181.75.108 (talk) 13:45, 6 January 2015 (UTC)
