When they say, "Stay tuned", I think of an earlier era when you actually had fine tuning on the TV and all tuners (gee, why did they call 'em that?) had analog dials and were user tuned to this station or that. Today the concept of tuning is all but lost. It's a push button world now. No young people close by to ask, so figured I'd ask here- what does "Stay tuned" mean to the under 30 crowd? Is it an abstraction?
