Jeopardy! used to work like this. Players would often buzz in immediately, hoping they would know the answer to the question (sorry, the "question" for the "answer" [1]). Since Alex Trebek still finished reading the clue, and most of the players knew most of the answers most of the time, this was a winning strategy. The producers changed to the current design in 1985.
