Though only 177 of the total 258 Olympic medals have been awarded so far, with Germany and the United States still battling for medal supremacy (as of February 23, the US had 26 medals and Germany 23), the real winner of the 2010 games has already been decided : American entrepreneurism.
From 1964 until 2002, the United States’ performance in the Winter Games could only be described as dismal. During that period, the US ranked no higher than 3rd and as low as 9th in the medal count and only earned between 5% and 10% of all medals awarded.

US Winter Olympic Performance Lagged from 1964 to 1998, but Has Improved Dramatically Since
So what happened to transform the US from Winter Olympics straggler to the champion of the games? If you think the reason is that a group of premiere Luge academies and Biathalon camps were established in the US to improve our training, guess again. The answer is that over the last 20 years, the US has innovated its way to the top of the medal count. Of the 15 Olympic sports contested in Vancouver, one-third of them made their Olympic debut during or after the 1992 games: Snowboarding, Freestyle Skiing, Short Track Speed Skating, Skeleton, and Curling. The three of them that award the most medals (Snowboarding, Freestyle and Short Track) were primarily invented in the US and the US remains the unquestioned leader in these events.

2010 Winter Olympic Sports by the Year They Debuted in the Olympics
The impact of these events on US performance cannot be overstated. Of the 2010 medals awarded in these sports, the US has won an astounding 25% of the total. Without them, instead of ranking 1st in the medal standings, the US would be tied for 2nd with Norway, 6 medals behind Germany.
