Punctuated Technological Change (PTC) occurs when a tipping point happens in various technologies.
For example: 1. Videos are introduced on the web such as the YouTube site. This causes a rapid transition during which many sites start to use embedded video content. Even newspaper sites now often use video content.
2. Compact flourescent light bulbs save energy and last longer. There use becomes very pervasive in a short period of time.
3. White LEDs become sufficiently inexpensive that they then replace the compact fluorescent bulbs, providing even better efficiencies and even longer life.
Other examples of Punctuated Technological Change are as follows:
Punctuated equilibrium is a theory in evolutionary biology which states that most sexually reproducing species experience little change for most of their geological history, and that when phenotypic evolution does occur, it is localized in rare, rapid events of branching speciation.
