The organisers of the UFC and MMA have certainly caught on to the broad appeal of the staredown, it's a major part of the lead up to fights. They now often have the two combatants staredown a number of times in the days before a major fight. Often the announcement of such fights is accompanied by the two fighters angrily glaring at each other as they stand nose to nose. I think its only a matter of time before a brawl breaks out during a weigh in, already they often press noses together and even butt heads.
