Changes in current CATI radio survey

  • The CATI survey was in 2006 reduced from 60,000 to 30,000 interviews per year and will still be the currency for local radio.

  • The radio survey is connected to the multimedia concept C&M, which makes it possible to do:

    • Multimedia analyses

    • Consumer analyses

    • Segmentation analyses

    • Other analyses


Portable people meter ppm in norway

Portable People Meter (PPM) in Norway

  • TNS Gallup and the Norwegian radio market have signed an agreement to start a PPM panel with 500 individuals.

  • All 5 national radio channels and a syndicate of 12 larger regional radio channels are measured. This constitutes 95% of radio consumption in Norway.

  • The five largest TV stations, which have a total market share of 90% of the viewing time among them, are encoded.

  • The different broadcasting platforms (FM, DAB, web) will be identifiable through PPM measurement.

  • PPM data is the official currency for buying radio airtime in Norway from August 2006.

The base station daily uploads of media and other information

The Base Station: Daily uploads of media and other information

  • Extracts data every night.

  • Recharges the battery.

  • Transmits data to the household hub.

    Offers immediate feedback to the survey participant:

  • Respondents are awarded "points" based on the time that the meter was in motion.

  • The points awarded are displayed daily on a message display on the base station. Every morning the points are also updated on the panel web site.

  • Other messages and questions to the respondents.


Ppm panel administration based on personal contact also through sms communication

PPM panel administration based on personal contact – also through SMS communication

  • Regular contact with panel members – weekly messages to all

  • Effective tool for incentive programme

    • News, campaigns, double points etc.

  • Special focus on ”Bad compliers”

3. CATI and PPM figures


Ppm gives 12 higher total weekly reach for radio

PPM gives 12%higher total weekly reach for radio

Percent

All days September 2006. Radio: 5 national and 12 local stations.

Storbyradioen: 12 local radios in Oslo, Bergen ,Stavanger and Trondheim.

The standard calculation of reach for PPM is 1 minute and for CATI it is at least 2 minutes in a 15 minutes interval.


Ppm gives 24 higher total daily reach for radio

PPM gives 24%higher total daily reach for radio

Percent

All days September 2006. Radio: 5 national and 12 local stations

Storbyradioen: 12 local radios in Oslo, Bergen ,Stavanger and Trondheim.

Calculation of time spent listening tsl

Calculation of time spent listening (TSL)

  • CATI in Norway

    • Respondent reports listening as at least 2 minutes in a 5-min interval.

    • If listening for at least 2 minutes, the 5 minute period is credited

    • Since the lowest reporting level is 15 minutes, and in order to coordinate TSL and Share, it was decided to credit 15 minutes TSL if listening reported at least one 5-minute period.

  • International

    • Lowest reporting level is most often 15-minutes. If listened to for at least 5-8 minutes in a 15 minute interval, the whole 15 minute interval is credited

  • TV-panel

    • Reporting level 1 minute basis for calculation of time spent viewing.

  • PPM in Norway

    • Reporting level 1 minute basis for calculation of time spent listening.

5. Conclusions

  • The compliance is methodologically acceptable

  • Weekly and daily reach increases

  • PPM gives a higher reach for all periods of the day

  • BUT does listening time drop?

  • PPM gives new sales and program opportunities
