tv audience measurement in Bulgaria

We started preparing the Television Audience Measurement project in Bulgaria in late 2011. Since then we  extended our coverage from Sofia to other cities, towns and villages and we have measured the TV audience in Bulgaria on a national level from the beginning of 2014.

Parameters of current TV audience measurement in Bulgaria since 2014


  • Measurement is carried out on a representative sample (panel) of households with television sets. All members are guaranteed anonymity.
  • The audience is measured for every active TV set in each household, and all members in the age 4+ participate in the measurement.
  • We also measure guests TV viewing (viewing of people visiting our panel homes as guests). This feature is included in TAM projects in vast majority of developed countries.
  • 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 Bulgaria, according to the current data of the NSI (National Statistical Institute).


  • 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.
  • The time-shifted audience of programmes is included in the TAM project, i.e. the audience of a programme after its TV broadcast time, over a horizon of 7 days.


  • Daily data are available every morning by 10:00 am, within 4 hours of the end of the previous TV day, which lasts from 6:00 a.m. to 6:00 a.m.
  • 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

  • Monitoring of the changes in the TV population is provided by the “Continual Survey”.
  • The Continual Survey for example examines the TV behaviour of Bulgarian households, their TV set equipment, TV channel reception etc.
