Ever wonder what's involved in producing the Olympics? Variety spoke with David Mazza, Senior VP and Chief Technical Officer, NBC Sports Group and NBC Olympics, about the "massive undertaking" that began shortly after closing ceremonies in London.

With a relatively short gap between the end of the Summer Games and the start of the next Winter Games, the first advance teams hit the ground in Russia just months after London wrapped. "We had people here for almost a year who were doing the advance planning, making deals with the hotels and the car companies," says Mazza.

It's a fascinating read that takes you behind the scenes of the biggest Winter Games in history.
