It sounds like your grandfather was and is technical. I'm talking about trends about nontechnical people. The question for me is whether nontechnical people are getting more technically literate.

For television, think about the broadcast spectrum and channels. These concepts become part of the literate vocabulary only afer the technology gets better established and people get better informed.
