# Where do we broadcast our questionnaires?

Our brand lift questionnaires are broadcasted across the entire digital advertising inventory. Practically speaking, we use programmatic media buying. This enables us to reach respondents who recall your ad and to collect spontaneous answers.

Anyone browsing on mobile apps or the web (desktop or mobile web) may receive our short questionnaires. The questionnaires are optimized and shown to unique respondents through a wide network of publishers.

Here is a short video showing how someone browsing the New York Times app can become a Happydemics respondent:
