During which phase of the hype cycle, developed by Gartner Inc., does interest wane as experiments and implementations fail to deliver on the hype of the peak?

Trough of disillusionment

Explanation:

The five overlapping stages in a technology hype cycle are:

Innovation Trigger : the possibility of technological breakthrough, implementation of the technology starts Peak of Inflated Expectations: success stories start to multiply, as well as failures, but nothing concrete. Trough of Disillusionment : If experiments and implementation continue to fail, interest wanes and producers tend to shake out or fail. Slope of Enlightenment : the potential benefits of the technological breakthrough start to multiply, other producers try to imitate the technology. Plateau of Productivity: technology starts to be adopted by the mainstream market
