Levi Strauss has released its most expensive commercial to date - a special-effects TV ad featuring people smashing their way through walls and running up trees. The multimillion advertising shows a young, jeans-clad couple encountering obstacles and jumping into the night sky. Reaction to these advertisments is almost instint. I can't tell you how these ads will be received by the younger generation Levis is targeting. But I can tell you this: As part of the targeted generation-the next time I'm out shopping for jeans, I may walk right past the 12 Gaps in my neighborhood and check out Levi's -- something I haven't done in a long time.
