Medialife has a post about a billboard ad campaign in London which syncs with car music.  MediaCom put together a campaign for the new Justin Bieber album.  When a Justin Bieber song is played on a Capital FM radio station in London, a Justin Bieber ad will run on digital billboards owned by Outdoor Plus in London.

Insider’s take: Expect to see more digital billboard ads which sync to music, the news (a Chas Schwab ad when the financial report comes on), the time of day (Starbucks ads in the morning), the weather (Home Depot ads prior to a snowstorm) and the traffic (You Would Be Home Now If You Lived Here ads during peak commute).
