Google (owner of YouTube) wants the world to know it now has a 411 directory service. Instead of advertising on TV, it's using YouTube. Make sense, right. I think it's an interesting example of how companies can use YouTube for advertising and how the medium (YouTube) shapes the message. The spot's more than an announcement--it's almost a 90 second informercial. It's a demonstration approach using Google geeks to show how Google 411 works. When's the last time a 90 spot on TV actually worked? However, here on YouTube because it's simple and resembles a user-generated video it seems to work. This is a telling example of how to keep a spot real, appealing and focused. It's a low-cost spot demonstrating how effective YouTube can be as an advertising medium.
