I was watching Jeopardy the other night and noticed that Alex Trebek before asking a contestant to pick a question he looked down and to his left. Then I noticed this a second time. I figured he was looking for an indication of which contestant should ask the next question, but wasn't aware of an indicator. After watching a bit more I noticed that on the bottom right (our left) of each players podium there is a little white light that lights to indicate the player who last correctly answered a question and the player who should choose the next one. Normally it is the person who answered the last question real easy, but when returning from the first break after the player interviews and if no one answers the question correctly it's nice to have an aid. Has this been obvious to others for a long time?
