PDFs can do a lot more than show static content. There was one time where Adobe strongly advocated for PDF to be the page format of what would come to be called "The World Wide Web". Where we have HTML now, Adobe wanted PDF. Thankfully that did not happen. But I suspect it would have made more sense technically than [whatever this mess is that we have now.]

A lot of things are possible in PDF.
