CD-based delivery systems did however, present advantages to software publishers. CDs were less expensive to manufacture than either video game cartridges or floppy disks and, unlike floppy disks, could not be readily copied. Publishers could therefore expect to achieve higher profit margins from the sale of CDs than were cur-rently the norm in the cartridge-based video game or floppy disk-based computer soft-
ware market. In addition, once a master copy was made, extra copies could be produced in small batch lots as needed.
