Back in the early days of the internet, there weren’t many internet applications. Instead, applications were overwhelmingly written for the Windows, Linux, and Macintosh operating systems. “Software delivery” often meant copying a binary to a server or building a blue-screen Windows installer and making that available on a CD-ROM to be sold in physical stores. (I remember when you had to pay extra to get your product delivered on 25 floppy disks instead of that CD-ROM.)
