Great ads, amusing parodies, and dry wit; the 30th olympiad has already brought us a microcosm of YouTubeness. "Olympics 2012" is a top rising search in the U.S. from the past 30 days and sports fever has spread across diverse genres.

We're only a few days in, but those first few days and last week's build up have delivered plenty of trending videos all over the YouTube map. First, and not surprisingly, many top brands have produced special ads for the games, some of which have been frequently shared and embedded.

The spots in the playlist below, which includes ads from Nike, P&G, Adidas, and more, have been seen over 15 million times total.



One of the most popular single videos to come from London this week was filmed not inside the games themselves, but from outside, where a dry and very funny Olympic worker expresses her enthusiasm about the start of competition. The clip already has 1.2 million views to date.



In the music genre, some of Team USA's top athletes created home-made lip-sync videos that spread quickly as the games kicked off. Below Women's Soccer "sings" some Miley Cyrus while U.S. swimmers take on Carly Rae Jepsen. Together, these videos have over 4 million combined views.


We'll be tracking all the trends coming out London over the next two weeks. Stay tuned!
