I first saw the word "technoporn" in Greg Egan's novel Distress. The protagonist used it as a pejorative and insult to his kidnappers. I use it in the context of pornography. Anything that glamorizes technology without merit, esp. in a prurient manner, counts as technoporn.
The best examples of technoporn appear on American television channels such as the Discovery Channel, in particular, the shows involving current or potential military hardware. If you don't work in the defense industry or military, then watching such video counts as indulging in technoporn.
