“The Magnificent Voyage of Christopher Columbus” (9 p.m., PBS): This special is adapted

“The Magnificent Voyage of Christopher Columbus” (9 p.m., PBS): This special is adapted (and upgraded to high-def) from the 1991 series, “Columbus and the Age of Discovery.” It recounts Columbus’ first Atlantic crossing, while a modern-day crew retraces the voyage in replicas of his fleet. Columbus’ big idea: to sail west to reach the East, and thereby chart a new trade route with China. Except it didn’t happen. Instead, he unwittingly ran into what became known as America, which really made waves.

“Journeyman” (10 p.m., NBC): Tonight’s episode of “Journeyman” is titled “Game 3” and it’s a reference to the 1989 World Series between the A’s and Giants in San Francisco that was abruptly halted by an earthquake. The plot has Dan traveling back in time to warn citizens of the imminent disaster.
