and images in their articles, again to familiarize more general aerospace readers. Because the journal encourages authors to provide an abundance of background information, Progress in Aerospace Sciences can easily be read and understood by readers with little experience in aerospace. Like many peer-reviewed journals, the majority of Progress in Aerospace Sciences''' readership comes online. In shifting from print to digital publication, the journal has adapted several content innovations, including interactive graphs and MATLAB plots, to engage readers. While the content and overall mission of the journal have stayed the same throughout its lifespan, there has been a notable shift in style. Older articles tend to be almost exclusively text-based, while recent articles feature an abundance of graphs and figures, making articles more accessible for an increasingly visual user base. Because of its recent innovations and the growth of the aerospace industry, Progress in Aerospace Science has experienced an increase in readership in the 21st century.
