There's nothing like a backwoods blood feud to excite television viewers on Memorial Day. The first part of the History network's miniseries Hatfields & McCoys was seen by 13.9 million viewers on Monday night, more than 17 million when the immediate repeat was added in, the Nielsen company said. The numbers held up for part two on Tuesday, which was watched by 13.1 million, Nielsen said. Those are huge numbers in the cable television world. No scripted series on the broadcast networks last week came close. By contrast, Fox's series finale of House last week reached 8.7 million people. Hatfields & McCoys had a couple of big-name stars in Kevin Costner and Bill Paxton and is airing over three nights in two-hour chunks. Broadcast television was dominated by competition shows again last week, led by the 21.5 million people who watched the American Idol finale on Fox. Dancing With the Stars and America's Got Talent also did well. Perhaps crowded by the marketplace, ABC's Duets finished a modest No. 23 in the ratings, with 6.8 million viewers. Fox's summer series So You Think You Can Dance also came out of the gate slowly, with 6.3 million viewers.
