I've seen these before, and I'm a wee bit suspicious that the items on the right side of "time" axis (which has no units) don't correspond to prior chart left side items.
In addition to selective recall and publication the unit-free time axis is key. That lets Gartner put SOA and "speech recognition" relatively close together on the graph, even though the maximal hype for SOA was about 3 years ago and for speech recognition it was 21 years ago.
There's one item in the cute info-free graphic that caught my fancy though. They list "idea management" as "post-hype".
Idea management?!
That one has completely passed me by but (thanks G) this blog post helped. Wow, I managed to almost completely dodge a very silly management fad. Until now. Yuck.
Clue to Gartner - ideas are easy.
