tv audience measurement in the cr

We have measured TV audiences in the Czech Republic since 29 April 2002, when we first started with the 5-year TV audience measurement project for the Association of Television Organizations (ATO). Read more about the history of TV audience measurement in the CR on the ATO website.

Selected parameters of TV measurement in the CR 2018–2022


  • Measurement is carried out on a representative sample (panel) of 1,900 households with TV sets (ca. 4,450 individuals), who are guaranteed anonymity.
  • The daily supply of data from at least 1,700 households is guaranteed.
  • The structure of the panel is regularly checked and modified, so that the sample of households matches the socio-demographic profile of households and individuals in the Czech Republic, according to the current data of the Czech Statistical Office (CZSO).


  • We measure the TV audience in households using a TV-meter (peoplemeter) system – this does not depend on the means of TV signal reception (DVB-T2, satellite, cable, IPTV, Internet).
  • We have developed our own non-invasive measurement technology – SimEar.
  • Audiomatching (a comparison of sound prints) is the dominant technology in our measurement.
  • Since 2013, the time-shifted audience of programmes has been included in the measurement project, i.e. the audience of a programme after its TV broadcast time, over a horizon of 7 days.
  • For the digital part of the project (PEM D) we use site-centric technology.


  • Daily data are available every morning by 8:00 am, within 2 hours of the end of the previous TV day, which lasts from 6:00 a.m. to 6:00 a.m., including Saturdays, Sundays and all national holidays.
  • The supplied data contain information about TV audiences accurate to the second, information about programmes, and socio-demographic information about households and the individuals living in them.


Continual Survey

  • This is carried out on a representative sample of at least 12,000 households yearly.
  • It is designed to monitor changes in the TV population in the Czech Republic.
  • It examines the TV behaviour of Czech households, their TV set equipment, TV channel reception etc.

Lifestyle Survey

  • Information about individual respondents is continuously enriched with information about their lifestyle and consumer behaviour from the Lifestyle Survey (LSS).
