Eye The Ticker said:@David Eduardo....What has changed the playing field are the new PPM ratings system. We're seeing stations which used to be at the top of the ratings report book after book. Now, with quarterly results being released, a very
distinct change is happening.
David, quite correct, I was in error. There are no quarterly reports. As you've mentioned, they appear about roughly once a month.
They appear every 28 days... in the case of Chicago, always a Monday unless there is a holiday. Arbitron does not go by calendar months, so what they call "Deccember" may be the third week of November to the second week of December; subscribers also get weekly reports in between the monthlies.
Agencies still average 2, 3, 6 books. Whatever helps them beat up stations on rates is what they use.
