It's been said already, the MONEY! Look at it this way, there is all the advertising during the commercial break and the fade ins / outs between segments. They are sure to keep getting the outfitters/guides name in at every opportunity. Are the shows fake, don't forget it's video, they don't want to edit in missed shots and screw ups. They have to fill a time segment with as much quality video as they can so of course you'll see the animal coming in and the shot that scores. It's for TV.
