You are the director of marketing and advertising at a big firm; you have a great job, flash car, big expense account. But there's something missing: You have no imagination. You are completely out of ideas. Your so-called team has bailed you out for the last few months, but, basically, the concept well is dry. What you need is something fresh, some way of reaching the young, high-spending set, a method of being present in their vacuous little lives on a near-permanent basis. But how? Oh, it's useless. Might as well retire now before they find you out.

Wrong! Now there is a way to be rarely out of the line of sight of those ABs with their massive disposable income, it involves attaching your logo to something so precious, so essential to their very being, that it never leaves them - their mobile phones.

Already popular in the Middle East, this new form of outdoor advertising involves getting a manufacturer to make up batteries for the most popular brands of mobile phone, with your ad embedded on the back. You then either give them out at selected events, or sell them at a discount. Punters will either use them as a spare, or, if you give them high-quality, long-lasting, vibrating versions, switch completely to your battery.

Mobile battery ads, various prices, are arrangeable by Brian Moran at The Telephone Centre, Dawson St, Dublin, and other retailers.
