There are reports that Jeopardy's executive producer wants to add a cash bonus of some sort to anyone who runs a category. It's not clear if (a) the answers have to be selected in order from top to bottom, although he did say that they needed to be consecutive, and (b) whether or not the money is included in the player's score, which I doubt.
I use "new" in quotes because the old weekly 1970s Fleming syndicated version had this; the first person to "correctly question all five answers" in a category won a prize. At first, it was a Chevy Vega; later, it became a trip to London with tickets to one or more West End shows.
