Arbitron Internet Broadcast Stations Weekly Top 50 (Feb 16 – Feb 22)

Notes:

1. TTSL (Total Time Spent Listening), sometimes referred to as Aggregate Tuning Hours (ATH), is the total number of hours tuned to a given station or network in the reported time period.
2. Cume Persons is an estimate of the total number of unique listeners who had one or more listening sessions lasting five minutes or longer during the reported time period. This estimate is derived using an algorithm that takes into account unique media player GUIDs, unique IP addresses and other variables during the reported time period.
3. The ratings may not reflect all tuning for the measured stations or channels since Arbitron may have received incomplete or unusable server data.
4. As Arbitron Internet Broadcast Ratings (powered by MeasureCast technology) transitions to a subscription-only service, some stations previously reported in the ratings have elected not to subscribe to the service and will no longer be included.
5. The 128K MP3 and all Ogg streams for Virgin Radio/1215 AM & 105.8 FM are not currently measured by Arbitron Internet Broadcast Ratings.
6. Due to a switch in Content Delivery Networks, tuning for The Adsertion Network is lower for the week of February 16.
