44.6. DG has argued that books, periodicals and journals would not be a part of same relevant market. The Commission is in agreement with this distinction that publication of journals, are different from books and other types of periodicals. Journals constitute an altogether distinct category on account of its unique characteristics, target readership, contributing authors and selection of content, as observed earlier. The distinction does not end here, but needs fine tuning to cover 'academic scholarly journals' which are distinct from professional journals. This distinction is on account of the fact that journal publication industry broadly caters either to the practicing professional or to the members of academia. The two types of journals differ vastly - academic publishing involves publishing of journals, which are aimed at researchers and academics, whereas professional publishing entails the publishing of periodicals, which are intended for professional use and/or provide information to practitioners and professionals. Thus, while the content of the former category could be new ideas / theories, the latter is the practical application of these thoughts. Academic journals, thus, constitute a distinct genre in publication.
