Background and Methodology

The rankings included in the November 2001 Arbitron Webcast Ratings are based on those stations and channels that have provided Arbitron with access to their server data. The ratings may not reflect all tuning for the measured stations or channels, since Arbitron may have received incomplete server data or some data that was not usable.

Arbitron Webcast Ratings debuted with October 1999 data as the world's first streaming media ratings service. Arbitron Webcast Ratings provides ratings for streamed media because webcasters need objective, third-party audience measurement to demonstrate the value of their audiences to agencies and advertisers. Arbitron Webcast Ratings is a server-side measurement, which captures all tuning to participating streamed media channels by compiling a near census of Internet tuning sessions.
