NEW YORK—A five-minute sampling of Hindi-language channel Zee TV stretched into a five-hour Indian TV marathon for Craig Mieritz, 23, Monday. "I have no idea what's going on, but I can't turn it off," the channel-flipping Mieritz said about a colorful, frenetic musical number on the soap opera Tum Bin Jaaoon Kahaan. "Maybe I'll just watch another minute..." Following the soap, Mieritz watched a Hindi pop variety show, 11 music videos, and the three-hour Bollywood epic Khuda Gawah, the remote in his hand the entire time.
