Wiley (owner of Blackwell) has published a list of the most popular articles in their journals in 2009. It’s hard to know what the definition means, since the criteria are not explicit (e.g. it includes articles published before 2009), and no rankings or numerical scores given.
However, scanning through the list is one article on open innovation — the Enkel, Gassmann and Chesbrough introductory article to September special issue on open innovation. The article — “Open R&D and open innovation: exploring the phenomenon” — is available for free download.
