Focus Groups in Media Research

There is no fixed rule; the guide is thematic saturation — running groups until additional ones stop yielding new themes. Many media studies use three to six groups of six to ten participants per relevant segment, with more groups when the population is diverse. The aim is analytic depth and coverage of the range of views, not statistical representativeness, so sample size is justified by saturation and design rather than by power calculations.

The defining difference is interaction. Focus groups generate data from participants responding to and building on one another, revealing how meaning is socially negotiated and what is shared or contested. Individual interviews provide depth on one person's views without group influence, and are better for sensitive topics or detailed personal accounts. Focus groups are more efficient and capture social dynamics; interviews offer privacy and individual depth. The choice depends on whether the social construction of meaning is part of the research question.

Reception researchers use focus groups to observe audiences decoding media in a social setting, often analyzing the talk through Stuart Hall's encoding/decoding framework to identify dominant, negotiated, and oppositional readings. Because interpretation is treated as socially situated, the group discussion is seen as a more natural site for meaning-making than an isolated interview. Landmark studies like David Morley's Nationwide audience work used group discussions to show how social position shapes how people read the same program.
