Measuring TV audiences requires state-of-the-art technology to ensure precise and accurate data is collected from the TAM panel homes, easily and effectively.Increasing numbers of channels, multiple broadcasting platforms, increased number of TV sets and remote controls per family have lead to a more complex TV environment.
Furthermore, the viewer is now faced with the possibility of utilizing the TV screen as a medium for VCR`s, including the option of time shifted viewing or video games, for accessing teletext, or as a personal computer offering on-line services and even more recently has access to personal television products like TiVO or Replay TV.
Within this dynamic environment, peoplemeters have proved themselves capable of measuring audiences with a degree of accuracy and detail, which surpasses previous alternative measurement systems.
The peoplemeters installed in the panel houses are the proprietary TVM series, entirely designed and developed in AGB Nielsen Media Research laboratories for all sister companies of the Group and 44,154 units (TVM1, TVM2, TVM4 series) are presently set up in 26,578 households worldwide, of which 20,516 are of TVM2 series and represent the most widely-operating pattern.
In Croatia AGB Nielsen Media Research installed the TVM4 meter, incorporating the latest technology, capable of measuring any type of broadcasting; including digital and analogue, free to air, cable and satellite, time shift viewing and teletext usage. The peoplemeters are installed on every TV set in the panel home. Each meter is capable of accurately monitoring, every second, 24 hours per day, 365 days per year, what is being viewed on each TV set, by whom, and of storing this data. The person, who is watching TV, registers itself by pushing the button (the number related) on the remote control. One meter in each home is then enabled to transmit all the stored data to the Production Centre, by means of the family`s telephone line, or a dedicated cellular (analogue and GSM) telephone line.
