This is a few weeks old, but worth a mention—the fun introductory spot for Google Fiber by ad agency Venables, Bell & Partners in San Francisco. Google Fiber is the experimental broadband network that Google is building using fiber optics—Kansas City, Mo., is the guinea pig for the first piece of it. The launch spot continues Google's now-familiar habit of using handmade, analog models as metaphors for digital processes.  In this case, Internet traffic is depicted as actual traffic, with little cars caught in traffic jams during the dial-up era, accelerating somewhat with broadband, and then finally exploding in a frenzy of speed on Hot Wheels-like tracks with Google Fiber—set to an infectious instrumental version of "Just What I Needed" by the Cars. VB&P teamed with production company 1stAveMachine on the ad—the same pair that produced the well-known gyroscope spot for Google Maps.  Check out some more videos for Google Fiber—which is supposedly 100 times faster than what most Americans have today—after the jump.
