Snippet from Wikipedia: Hype cycle

The hype cycle is a branded graphical presentation developed and used by the American research, advisory and information technology firm Gartner to represent the maturity, adoption, and social application of specific technologies. The hype cycle claims to provide a graphical and conceptual presentation of the maturity of emerging technologies through five phases.

The Gartner hype cycle has been criticised for a lack of evidence that it holds, and for not matching well with technological uptake in practice.
