If you like a commercial, odds are decent that it came from Wieden + Kennedy, perhaps most famous for creating "Just Do It". Remember: heading into the '90s, Reebok dominated Nike. The coining of "Just Do It" and the attendant campaigns were perhaps a major factor in propelling Nike to the forefront of their market. W+K also made Honda's famous "cog" commercial.

They're also doing some work that may be interesting to the HN crowd over at http://www.wk.com/incubator. If I were a far more brilliant and creative person, I'd love to just hang out with their directors: they do a consistently good job in an area that's very hard to get right again and again over time.
