Innovation in the computer hardware, storage, and software industries continues at a rapid pace, usually yeilding greater storage and processing capacities at lower cost. Devices, processes, and software for recording and storing information are being replaced with new products and methods on a regular three- to five-year cycle, driven primarily by market forces. Records created in digital form in the first instance and those converted retrospectively from paper or microfilm to digital form are equally vulnerable to technological obsolescence.
