Home Devices

Evolution in media and multimedia equipment in French households

What are the trends, successes and developments in multimedia equipment?

The devices are fundamental to all use; they are the sine qua non for all developments in media and multimedia behaviours.

The Home Devices study observes the evolution in equipment in households in France

  • Collect details about French household devices
  • Determine the profile of those with devices
  • Target communications according to household's profiles
  • Measure the development in device inventory

Home Devices is a study performed every quarter among a representative sample of 10,000 households in France (or 40,000 households per year). An original method to obtain the most precise description possible of equipment installed in French households.

Each quarter a single source on the media and multimedia equipment of French households is provided:

  • Number of households with internet access
  • Emerging equipment
  • Profile of household over or under-equipped... Over 50 devices and types of subscriptions are studied in detail.

The list of equipment studied is updated every quarter according to the latest innovations.

Two different interpretations of data: results on households and results on individuals

Available as:

  • quarterly summary
  • online interface

Four publications per year on mature and emerging goods over four major sectors:

  • TV
  • Computer technology
  • Internet access
  • Telephony

Quarterly results published on the online interface, on the 25th of the month following the end of the quarter.
