At home I have TV (a zillion channels of standard broadcast and cable), wireless Internet (websites, blogs, videos, email, instant messaging), audio (the radio, my stereo, my iPod and Podcasts), books, magazines and newspapers.

In my car I have only audio and – for visual advertising - outdoor (those pesky outdoor boards, street furniture and transit.)

No wonder outdoor is booming according to the Outdoor Advertising Association of America.

“Outdoor advertising increased by 9.8 percent to $3.2 billion last year, according to TNS Media Intelligence. And while TNS recently lowered its growth projections for the overall U.S. ad market for 2006, it increased its forecast for outdoor to 7.7 percent growth. A number of leading advertising seers, including WPP Group Chairman-CEO Martin Sorrell and Carat CEO David Verklin have predicted that out-of-home media would be among the most explosive growth media over the next several years, second only to online.”
