Avoiding burn-in (plasma) and brown-in (LCD). A plasma display, even today's models, will get burn-in if the display is only used for 4x3 content. An LCD display, despite what most uninformed people believe, will get brown-in if the display is only used to display 4x3 content.

There are (close to) 4x3 LCD displays, but they are, relatively speaking, small and are best suited for use as a computer monitor. There was a company (can't remember the manufacturer) that made a 42" plasma display that had a 4x3 aspect ratio. That was years ago and I haven't seen it advertised since then.

I wish we could make a push for ALL broadcasts in the 16X9 format, but as they say, LOL. Any TV I purchase MUST be able to keep the 4X3 format to fill the screen by cropping the top and bottom, NOT streching it to fit the screen.

  I don't even accept the top/bottom cropping. None of my more recent 16x9 TVs do that unless you choose it... I do have an old Sony that crops several rows of 4:3 pixels top/bottom, uncontrollably by me, just enough to annoy me with old movies lol; in those days it was less unacceptable on a WS display.
  
  One thing though: if a few rows top/bottom aren't cropped, in some 4:3 digital TV broadcasts you can see some "junk" up/down there. I was told why, but forget... Many TVs (like my main one) have a slightly less optimal viewing mode that will cut them off and not do much other harm, good enough for a typical TV broadcast (after all, the best are 1080i 16x9 anyway).

    There are extra lines in video that serve as a home for such things as: synchronization, vertical retrace, closed captioning data and some timecode material. Unless you are in the industry and make use out of it, a non-technical term for such things could probably be "non-picture crap".
