Sustaining technology
The term disruptive technology was coined by Clayton M. Christensen to describe a new, low cost, often simpler technology that displaces an existing sustaining technology.
Disruptive technologies are usually initially inferior to the technology that they displace, but their low cost creates a market that induces technological and economic network effects that provide the incentive to enhance them to match and surpass the previous technology.
Examples of successful disruptive technologies:
- mass-market cellular telephony
- the Internet protocol
- digital cameras
- personal computers
- voice over IP
- EIDE/UDMA hard drives
- open-source software
- ADSL
- the automobile
- Compact discs

Examples of sustaining technologies being displaced:
- fixed-line telephony
- proprietary or fixed-configuration networks
- photographic film
- mainframe computers
- analog and fixed digital telephone systems
- SCSI hard drives
- proprietary software
- ISDN
- railways
- amateur radio

Not all technologies promoted as disruptive technologies have actually prospered as well as their proponents had hoped. However, some of these technologies have only been around for a few years, and their ultimate fate has not yet been determined.
