In previous research, attention is given to the travel and translation of ideas in order to capture how ideas flow and by whom. External actors, so called carriers, promote certain ideas and discard others, further playing a significant part in the institutionalization of ideas. The multitude of different carriers, their different promotion techniques and interconnectedness call for the need to study them in relation and differentiation to one another. Through a qualitative content analysis of documents, interviews and videos, we present a case study on carriers promoting the current idea of a circular fashion system. The investigated carriers are consultants, media, academia, NGO/NPOs and gurus. Alongside the previously identified sequential and parallel modes of translation, we find carriers promoting the travel of an idea jointly. Among the carriers studied, the findings reveal evidence of (1) linkages through cross-referencing, and (2) collaboration through funding, assignment and co-writing. Coupling the notion of blurred boundaries between carriers with ecologies of translation, the study finds carriers situating in different contexts and constellations, forming hybrids and hierarchies. Providing such evidence of a more complex scenery, we argue that the landscape in which carriers promote an idea is best understood as constituting webs.
