Remind me, exactly what was a TV? (Score 1)

I have some vague recollection of it being a 20th century device that was a limited purpose monitor. I'm not sure I have space on my desk for a display device that can only be used with one source. It strikes me that running a separate display device just for this "television" service is inherently somewhat energy and resource wasteful. A truly energy efficient "TV" is a monitor that is also used for non-TV purposes.
