The prevention of unauthorized copying of software or media. From the 1950s to the 1980s, software copy protection was not an issue.

As desktop computer software became more complex, technical support became just as important, but could be obtained from many sources, not just the vendor of the product.

In the early days of floppy disk-only computers, some software copy protection methods were used, but "copy buster" programs were quickly developed to break them. When hard disks became the norm, software copy protection was abolished. In order to defragment a hard disk, files had to be easily copied from one part of the disk to another.
