The Megajournal Lifecycle
Megajournals have been at the heart of the Open Access (OA) publishing model, spearheading its growth over the last 15 years. Titles such as PLOS ONE (ISSN: 1932-6203) and Scientific Reports (ISSN: 2045-2322) have been enormously influential and commercially successful. Nonetheless, the commercial success of megajournals is not guaranteed and their long-term performance has been occasionally unreliable, introducing uncertainty in an industry that has been particularly attractive to investors for its ability to generate low but sustainable growth.
