The Olympic Games are one of the most-watched telecasts in the world, thanks in part to the massive production efforts that go into broadcasting the event far and wide.

That's no different for this year's Winter Games, which opened on Friday in Pyeongchang, South Korea. The event is an undertaking that costs billions of dollars and includes an NBC telecast that stretches across several weeks and time zones.

Some of the staggering numbers behind this year's games tells the story of an event that is constantly trying to outdo itself. NBC is pulling out all the stops and sending the most-ever number of commentators to provide insight and commentary for a record 2,400 hours of coverage.

Read below to learn more about other record-breaking stats.

The Games

February 9th, 2018 -- Date of the Pyeongchang Winter Olympics opening ceremony.

February 25th, 2018 -- Date of the Pyeongchang Winter Olympics closing ceremony.

$10 billion -- The estimated cost of the Pyeongchang Winter Olympics. The amount is roughly the GDP of Madagascar. That's five times less than the 2014 Sochi Olympics, which was estimated to be the costliest ever.

2,925 -- Number of athletes who will compete in the games. The US is sending 244 athletes, the largest athlete delegation in Olympic Winter Games history.

39 -- The age of the oldest US winter Olympian: Hockey player, Brian Gionta. Last year, he played his 1000th game in the NHL.

50 - Miles the city of Pyeongchang is from the demilitarized zone that separates the south from North Korea. The DMZ is a border that splits the country in two, it's heavily fortified and is roughly 160 miles long.

The Telecast

5 -- NBCUniversal networks that will broadcast the games (NBC, NBC Sports Network, CNBC, USA and the Olympic Channel).

$900+ Million -- Money generated in national ad sales for Pyeongchang, which is a Winter Games record. NBC Universal said that it expected its Super Bowl LII coverage to generate $500 million in ad revenue.

2,000 -- Number of NBC employees working in Pyeongchang for the games.

2,400+ -- Hours of game coverage. This is the most ever for a Winter Olympics, according to NBC. The last Winter Games to hold this record was the 2014 Sochi Winter Olympics.

127 -- Miles of cable that will be used by NBC for the games. That's roughly the distance between Los Angeles and San Diego. For the exceptionally athletic, you'd have to run the length of Manhattan roughly nine times to hit 127 miles.

126+ -- NBCUniversal's coverage hours, per day. The network said that's nearly triple the entire coverage of the 1976 Innsbruck Winter Olympics on ABC (43.5 hours).

89 -- Number of NBC Olympics commentators. The most-ever for a Winter Olympics, according to NBC. That includes Mike Tirico in his first go as Olympics host, former Olympians like skier Bode Miller, figure skaters Tara Lipinski and Johnny Weir, and Katie Couric, who makes her return to NBC to co-host the opening ceremony with Tirico.

54 -- Years since NBC's first Olympic broadcast, which was the 1964 Tokyo Games. NBC's Olympics contract runs through 2032.
