Welcome to GAMMA

The Global Alliance for the Measurement of Media Audiences (GAMMA) is comprised of four currency-grade audience measurement bodies, namely BARC (India), Médiamétrie (France), Numeris (Canada) and Video Research (Japan). Together, they have formed an international alliance to chart a course for the future of video audience measurement.

Through the creation of GAMMA, individual members will leverage their collective knowledge and expertise to advance audience measurement solutions in their home country as well as across the wider global marketplace. GAMMA intends to act as a key conduit towards a more consistent, transparent, standardized and interoperable audience measurement system. The four founding nations collectively account for a total population of more than 1.5 billion and represent a combined advertising spend of USD 78 billion.
