There is a moment of foreshadowing at the end of "Battle at Kruger," the eight-minute African safari video that has drawn more than 30 million views on YouTube.
David Budzinski, a tourist from Texas, has just recorded a stunning scene straight out of a wildlife documentary. A small pride of lions and a crocodile have pinned down a cape buffalo calf, prompting an angry herd of buffalo to fight off the predators and save the babe. A fellow traveler remarks, "You could sell that video!"
After returning home, Mr. Budzinski tried, but National Geographic and Animal Planet were not interested. Only after the battle -- alternately terrifying and heart-warming -- became one of the most popular videos in YouTube's history did the buyers come calling. Last summer the National Geographic Channel purchased the television rights to the video, and on Sunday at 9 p.m. Eastern time, it will devote an hour to a documentary deconstructing the drama.
