Why Them? Discovery’s portfolio is diverse, and these high-energy leaders split duties presiding over some of its most notable networks. O’Neill has polished Discovery’s roster to now include five of the top 10 unscripted shows among men 25-54, including “Gold Rush,” “Moonshiners” and “Amish Mafia.” Sister show “Breaking Amish” and that special little slice of Americana, “Here Comes Honey Boo Boo,” are shining on TLC.
