To put this in terms Bill would use...
Translation for the rational: under fire for local measurement issues, Nielsen has some good data to spin at the national level.
Translation for the crazy: last week Nielsen counted slightly more viewers for the shows you love that hardly anyone else watches, while counting slightly fewer viewers for the shows you hate that are watched by many more people than the shows you like. But, aside from last week, for the last 5 years you've been screwed!
For the week ending Nov. 15, the sample performance indicator (SPI), which measures the percentage of people who were asked to join Nielsen’s sample and are producing useable data, reached 45.9 percent, its highest levels since May 2004. Year-to-date, the average SPI is 44.4 percent.
