Previous research has investigated social media phenomena by ex-amining collective archival data (e.g., McQuarrie, Miller, & Phillips, 2012). However, in the context of Instagram, lurkers do not create content and, therefore, reviewing archival data was not possible. In addition, previous research on lurking mainly uses interviews (Nonnecke & Preece, 2000), online surveys (Kefi & Maar, 2018), or experiments (Schlosser, 2005) to understand lurkers and their beha-viors. To this end, the first author (a millennial and Instagram user) conducted 16 semi-structured interviews (McCracken, 1988) with as-pirational luxury millennial consumers who have never or seldomly purchased a luxury product/service in the past. Respondents were European citizens, aged 20–34 years, and were selected according to two criteria: (1) they followed luxury brands or other luxury-related content (e.g., created by wealthy social media influencers [SMIs]) on Instagram, and (2) their behavior on Instagram corresponded to a lurker (i.e., seldom post content, if at all, or create content). We re-cruited respondents through snowball sampling via social media plat-forms (e.g., Instagram, Twitter, Facebook). We conducted the inter-views from January to September 2018, face-to-face or remotely via video link. Interviews lasted between 30 and 90 min, were recorded (totaling 14 ½ h), and were transcribed verbatim. Table 2 provides a summary of the respondent profiles. Data collection ended when sa-turation was achieved with no new themes emerging from the inter-views (McCracken, 1988).
