The World's Favourite...ad

I love innovation, especially where it's clever and touches an unserved market. If you get all three of these - the marketing trifecta - then it's a huge win.

I think British Airways and their Ad Agency have accomplished this feat with this contextual use of an old medium - billboards : - http://www.youtube.com/watch?v=j7vq7yS4ghE 

The clever things about this abound.  There are a series of variations in the video's launched on the board; it actually interfaces with the plane flying overhead so the results aren't random or canned, they are real.  And its engaging.

The use of new technologies to make a big impact is rare these days - there are lots of great ideas but many don't find traction with customers.  This one is simple and very effective.  Way to go BA.
