Leo Burnett here in Toronto have done a really strong job with their follow up to the 2012 Local Attack Campaign.
They've taken over some key out of home locations to create a really strong message that Yellow Pages can help you find things.
Now, I wont lie, I have not installed the app - and I'm likely not going to - Mostly because the past experiences with the YP have been rather poor. Nonetheless , I think the work and messaging is fun and playful - It's also really smart given how much work / copywriting went into each place, and ensuring the message was exactly right for each placement.
Everyone saw the Radioshack commercial, where the 80's called - they want the store back. But I don't thin many people noticed that they also released some individual spots online, including a minute long commercial with Alf, being shown a new cell phone and it's capabilities. Check it out!
