I watch the Financial news network on my Plasma all the time with that stock ticker running across the bottom of the picture. Sometimes the sets on 20 hours or more a day (I sleep with the TV on and it's located in the bedroom). I've had no issues with burn in, but I use the picture orbiter. Now, when I turn the set off in a dark room, I can see the picture for about 3-5 minutes until the gas cools off, but that's not burn in.
