Advertising-like messages delivered through the Internet now go well beyond simple banner
adverts or home pages, and are they being more targeted for interactive. Keywords used
in searches and e-mail can now trigger related adverts. Promotions too are delivered over
the Internet, with some web sites devoted only to online promotions. Mobile marketing enables
advertisers to send messages directly to cell phones and other wireless mobile devices.
With prior permission from cell phone users, messages can be highly targeted and exposure
tracked. It is even possible to direct messages to cell phones from outdoor billboards.
