The lure of live, high-stakes drama was evident in Sunday’s ratings, as Discovery’s “Skywire Live with Nik Wallendaspecial was easily the night’s most-watched program.

According to Nielsen, tightrope walker Nik Wallenda’s “skywire” scoot 1500 feet over the Grand Canyon drew 13 million viewers for its 23-minute walk segment (9:38-10:01 p.m. ET). The next most popular program of the night, CBS’ “60 Minutes,” nabbed 8.2 million.
