Book excerpt: The book offers new theoretical perspectives on innovation, analyzes innovation processes in diverse innovation fields, and presents case studies that reflect the diversity of innovations fields. To what extent and in what sense does innovation characterize our societies today? Innovations are no longer limited to the economic sphere; we find them in almost all areas of society today. Diverse actors generate innovations in different, increasingly reflexive ways. New concepts, practices, and institutional forms such as open source, crowdfunding, or citizen panels expand the spectrum.
