A movie of Team U.S.A. accepting the gold is available on the BBGA site.
I haven't yet found any information on who won silver and bronze, nor have I found pictures yet. If anyone finds any, please post a link to them in the comments below!
Update: According to this article, France took second and Japan took third.
