Discovery ChannelSometimes TV can be as basic as a football game, a long-distance police chase or a guy walking on a wire.

When Nik Wallenda walked across the Niagara Falls for ABC it was a big event, but he had to wear a harness. For cable, no such problem. So he walked over a gorge near the Grand Canyon last year for the highest ratings in Discovery history. Tonight, he walks between two towers across the Chicago River. For the first part of “Skyscraper Live with Nik Wallenda” (Discovery, 7 p.m.), he’s to cross more than two city blocks, 50 stories up, uphill on a wire at a 15 degree angle. For the second part of the walk, he’ll be blindfolded. The whole thing is expected to run two hours and twenty minutes — on a 12 second delay, just in case anything goes wrong.
