2.3 Billion By 2009

From ZDNetblogs 2.3billion wireless subscribers by 2009

Worldwide, wireless subscriber growth is experiencing robust expansion after several years of slower growth due to the economic downturn of the last few years, reports In-Stat. By 2009, the research firm forecasts the worldwide wireless market will grow to more than 2.3 bln subscribers.

That's 2.3 billion TV sets, PC monitors, billboards, radios, magazines. Maybe advertisers need to think of it in those terms in order to realize how big mobile advertising will be.

If you asked ANY brand manager, "would you like to advertise to 2.3 billion screens?", what do you think the response would be.
