TV audience measurement

We measure TV audience in the CR and in Armenia (via licence). We are part of the global Nielsen group which provides TV audience measurement in more than 30 countries around the world.

We have measured TV audiences in the Czech Republic since 29 April 2002, when we (as Mediaresearch) 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.

The TV audience measurement roject consists of two main parts: 1. PEM TV (television part), i.e. measurement of audience of live and time-shifted viewing on TV sets, 2. PEM D (digital part), i.e. measurement of audience of TV and other video content of the involved media on digital devices.


TV part (PEM TV)

  • Measurement is carried out on a representative sample (panel) of 1,900 households with TV sets (ca. 4,350 individuals 4+), 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).

Digital part (PEM D)

  • Online audience measurement is not carried out using a panel, but tracks online users (using the "census" method) who watch video content online.
  • Digital audience measurement is carried out in compliance with all legal standards and industry codes of ethics.


TV part (PEM TV)

  • 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 technologySimEar.
  • 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.

Digital part (PEM D)

  • The digital part of the project (PEM D) is based on the site-centric technology.
  • The players of the participating broadcasters (in browsers and applications) are equipped with measurement codes that record each video view, the video's description and measure the time spent watching. The data is then included in the overall viewership results.


The results of PEM TV and PEM D can be combined. E.g. the proportion of viewers watching a given programme live on TV / live online / time-shifted on TV / time-shifted online can be calculated.

TV part (PEM TV)

  • 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., every day 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.

Digital part (PEM D)

  • Daily data are available to subscribers by 12:00, every day including Saturdays, Sundays and all national holidays.
  • The data include information on the audience of specific programmes, type of viewing (live/archive), time spent watching on different devices and platforms (PC, mobile, tablet, smart TV / web, apps, HbbTV). Using statistical modelling, it is then possible to estimate the audience e.g. in different age groups, among men and women, etc.


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).
